Which of the following is true regarding a series circuit? The current flow is the same through all resistors. Which of the following is true regarding a parallel circuit? It has more than one path for current to flow. Which of the following is true regarding a series-parallel circuit? If a circuit is reduced to an equivalent series circuit, the total resistance is found by adding the loads. Two branches of a circuit (R1 and R2) across a 120V power line draw a total line current of 30A. Branch R1 takes 15A. What is the current I2 in branch R2? 15A Who stated that the current entering a point must equal the total current leaving that point? Kirchoff In a circuit with an applied voltage of 10V and voltage drops of E1 = 2V, E2 = 5V, and E3 = ?, the value of E3 must be____________. 3V

You can use Ohm's law to find the value of each branch current in a parallel circuit. True Find the total resistance in a series circuit with three resistances of 100Ω, 20Ω, and 30Ω. 60 In a parallel circuit, the voltage across each path is equal to the _____________. applied voltage A resistor of 32Ω is in parallel with a resistor of 36Ω, and a 54Ω resistor is in series with the pair. When 350V is applied to the combination, the current through the 54Ω resistor is ____________. 4.93A A 242Ω resistor is in parallel with a 180Ω resistor, and a 420Ω resistor is in series with the combination in a 27V circuit. A current of 22mA flows through the 242Ω resistor. The current through the 180Ω resistor is _____________. 29.6mA Which statement is not correct relative to Kirchhoff's current law? Kirchhoff's laws apply to current only.

The total resistance of four resistors in parallel with values of 3, 10, 25, and 50 ohms is _____. 2.03 ohms According to Kirchhoff's voltage law, the total voltage drop in a circuit is equal to the _____. voltage of the power source A ______________ contains only one path for current flow. series circuit _____________ contains two or more parallel paths through which current can flow. Parallel circuits ______________states that the total amount of current flowing through a parallel circuit is equal to the sum of the amounts of current flowing through each current path. Kirchhoff's current law _____________ states that the sum of all the voltage drops in a circuit is equal to the source voltage of the circuit. Kirchhoff's voltage law
