It typically consists of two or more coils of wire, which are magnetically coupled to each other. When an alternating current flows through one coil, it creates a varying magnetic field, which in turn induces a voltage in the other coil, allowing electrical energy to be transferred from one circuit to the other. be able to interpret the function and states of a basic electrical circuit - CorrECt AnSWEr-- study basic electrical circuits Define voltage - CorrECt AnSWEr-an electromotive force or potential difference expressed in volts.
explain how to measure continuity - CorrECt AnSWEr-To test for continuity, touch one probe to one end of the circuit, and the other probe to the other end of the circuit. If the circuit is complete and unbroken, the continuity tester will indicate that there is continuity by lighting up a light or sounding a buzzer. what is a DMM - CorrECt AnSWEr-Digital Multi Meter M(ohms) - CorrECt AnSWEr-a unit of electrical resistance that is equal to one million ohms (1,000,000 ohms). It is often used to measure the resistance of high-resistance components or circuits, such as insulation resistance in electrical cables. K(ohms) - CorrECt AnSWEr-A kiloohm (kΩ) is a unit of electrical resistance equal to 1000 ohms. It is commonly used to measure the resistance of electronic components, such as resistors, in circuits. Mega Amps - CorrECt AnSWEr-A megaamp (MA) is a unit of electric current equal to one million amperes. It is a large unit of measure typically used to describe the flow of electrical current in high-power electrical systems micro ampere - CorrECt AnSWEr-one millionth of an amp Series resistance equation - CorrECt AnSWEr-Rt=R1+R2+R Parallel resistance equation - CorrECt AnSWEr-1/Rt = 1/R1 + 1/R2 + 1/R Kirchoff's Voltage Law - CorrECt AnSWEr-The total of all voltage drops in a series circuit must equal the voltage supplied by the battery Define power - CorrECt AnSWEr-rate of energy transfer (P)
calculate Parallel current - CorrECt AnSWEr-Total current = sum of the currents through each resistor calculate series current - CorrECt AnSWEr-Total current = current through each resistor thermal circuit breaker - CorrECt AnSWEr-Thermal circuit breakers use a bimetallic strip that heats up and bends when a certain level of current flows through it. When the strip bends far enough, it trips a mechanism that opens the circuit and interrupts the flow of current. To reset a thermal circuit breaker, you typically need to flip the switch on the breaker to the "off" position, then back to the "on" position. magnetic circuit breaker - CorrECt AnSWEr-Magnetic circuit breakers use an electromagnet to trip a mechanism that opens the circuit when a certain level of current flows through it. The electromagnet becomes stronger as the current increases, and eventually trips the mechanism when the current reaches a certain level. To reset a magnetic circuit breaker, you typically need to push the reset button on the breaker. Electromagnetism - CorrECt AnSWEr-Electromagnetism is the physical phenomenon in which electrically charged particles interact with each other through the force of electromagnetism. This force arises from the interactions between electric fields and magnetic fields, and can be observed whenever electrically charged particles are in motion. Define inductance. - CorrECt AnSWEr-An induced voltage which is opposite in direction to the applied voltage. henry (H) effect of an inductor in an AC system - CorrECt AnSWEr-an inductor acts as a resistor to AC current. It opposes changes in current and causes the current to lag behind the voltage in the circuit. This property is known as inductive reactance, and is measured in ohms. effect on an inductor in a DC system - CorrECt AnSWEr-an inductor acts as an open circuit to DC current. It does not allow DC current to pass through it and effectively blocks the flow of current in the circuit. This property is known as DC resistance, and is measured in ohms. total inductance equation - CorrECt AnSWEr-Total inductance (L) = L1 + L2 + L3 + ...
effects of a capacitor in an AC system - CorrECt AnSWEr-allowing alternating current (AC) to pass through it. This is because a capacitor's impedance (resistance to AC) increases with frequency, so at low frequencies it acts as a short circuit and allows current to pass through easily, but at high frequencies its impedance increases and it acts as an open circuit, blocking the flow of current. calculate total capacitance - CorrECt AnSWEr-add capacitances calculate total capacitive reactance - CorrECt AnSWEr-X_C = 1 / (2 * pi * f * C) X_c= capacitive reactance in ohms f= frequency in hertz c= capacitance in farads calculate total load on an AC circuit with capacitors - CorrECt AnSWEr-X_C = 1 / (2 * pi * f * C) calculate the time to charge and discharge a capacitor - CorrECt AnSWEr-time=RC R= resistance of circuit C= capacitance of capacitor in farads capacitors in power supply - CorrECt AnSWEr-Capacitors are used in power supplies to store electrical charge and to release it when the input voltage drops or when there is a sudden increase in current demand. This helps to smooth out fluctuations in the input voltage and to provide a steady flow of current to the load. inductors in power supply - CorrECt AnSWEr-inductors are used in power supplies to store energy in the form of a magnetic field. When the input voltage fluctuates, the magnetic field in the inductor will also fluctuate, which can generate a counter-voltage that opposes the changes in the input voltage. This helps to smooth out the voltage fluctuations and to provide a more stable output voltage.
operation of a variable resistor - CorrECt AnSWEr-A variable resistor, also known as a potentiometer, is a type of resistor that allows the resistance to be adjusted. It consists of a resistive element with a wiper that can be moved along the element to change the resistance. how to troubleshoot a short circuit - CorrECt AnSWEr-1. First, make sure that the power is off and that all safety precautions are followed.
- Locate the source of the short circuit. This could be a damaged wire, a loose connection, or a faulty component such as a resistor or capacitor.
- Check the circuit for any visible signs of damage, such as burnt or melted components, or frayed or exposed wires.
- Use a multimeter to test the resistance and continuity of the circuit. A short circuit will typically have a very low resistance, so if you see a reading that is much lower than expected, it could indicate a short circuit. three basic steps for troubleshooting an open circuit - CorrECt AnSWEr-1. First, make sure that the power is off and that all safety precautions are followed.
- Locate the source of the open circuit. This could be a broken wire, a loose connection, or a faulty component such as a resistor or capacitor.
- Use a multimeter to test the resistance and continuity of the circuit. An open circuit will typically have a very high resistance, so if you see a reading that is much higher than expected, it could indicate an open circuit. operation of a transformer - CorrECt AnSWEr-A transformer is an electrical device that is used to transfer electrical energy from one circuit to another through inductively coupled conductors, or coils. It works on the principle of electromagnetic induction, where a changing magnetic field in one coil generates a voltage in the other coil. Transformer Output Voltage Formula - CorrECt AnSWEr-V_out = V_in * N_secondary / N_primary N= turns of coil how to troubleshoot a transformer with a dmm - CorrECt AnSWEr-1.
