Laboratory Policies :

 Each lab session lasts two periods and starts promptly. A brief introduction may be given by the instructor at the beginning of the lab.

 Everybody has to finish on time, so please time yourself carefully. Doing the pre-lab can save you a lot of time.

 Review the material prior to coming to the lab; consult the textbook(s) if required.

 Calculate the anticipated theoretical results, and get an idea of the approximate range and scale of the quantities you will be measuring.

 All laboratory work has to be completed during the designated lab period.

 Attendance at your regularly scheduled lab period is required. An unexpected absence will result in the loss of credit for your lab.

 Report: Neatness, organization, and completeness will be rewarded. Points will be deducted for any part that is not clear.

 Reports Due Dates: The lab reports are due the following week at the beginning of your lab session.

 Dress code: Please carry your ID card with you always. Wear White coat and shoes for the lab

Assessment:

Lab Performance - 30% Pre lab - 05% Post Lab - 05% Record - 05% MCQ/Quiz/Viva Voce – 05% Model Exam - 10% Final exam - 40%

Systems of Tests:

Regular laboratory class work over the full semester will carry a weightage of 60%. The remaining 40% weightage will be given by conducting an end semester practical examination for every individual student.

VERIFICATION OF KIRCHHOFFS LAWS

Aim: To verify Kirchhoff’s current law and Kirchhoff’s voltage law for the given circuit.

Apparatus Required: S.No. Apparatus Range Quantity 1 RPS (regulated power supply) (0-30V) 2 2 Resistance (^330) , 220 1k 1 each 3 Ammeter (0-30mA)MC 3 4 Voltmeter (0-30V)MC 3 5 Bread Board -- 1 6 Connecting Wires -- Required

Statement:

KCL: The algebraic sum of the currents meeting at a node is equal to zero. KVL: In any closed path / mesh, the algebraic sum of all the voltages is zero.

Precautions:

1. Voltage control knob should be kept at minimum position.
2. Current control knob of RPS should be kept at maximum position.

Procedure for KCL:

1. Give the connections as per the circuit diagram.
2. Set a particular value in RPS.
3. Note down the corresponding ammeter reading
4. Repeat the same for different voltages

Procedure for KVL:

1. Give the connections as per the circuit diagram.
2. Set a particular value in RPS.
3. Note all the voltage readings.
4. Repeat the same for different voltages

KVL – Theoretical Values Sl.No. RPS Voltage KVL E 1 E 2 V 1 V 2 V 3 E 1 = V 1 + V 2 V V V V V V 1 2 3

Result: Thus Kirchhoff’s voltage law and Kirchhoff’s current law were verified both theoretically and practically.

POST LAB

1. What is regulated power supply?
2. Explain why an ammeter must be connected in series with a resistor.
3. What modification is done in galvanometer to convert it into an ammeter?
4. How to calculate the error value for the conducted experiment?

PRELAB

1. a) Read the color codes of the resistors given for this experiment and determine the

nominal value and tolerance of each carbon resistor and record them.

b) Measure the values of the resistors with the digital multimeter and record them.

2. Define linear network.
3. Explain additivity and homogeneity principles.

Experiment No. 2 Date :

VERIFICATION OF SUPERPOSITION THEOREM

Aim: To verify the superposition theorem for the given circuit.

Apparatus Required: Sl.No. Apparatus Range Quantity 1 RPS (regulated power supply) (0-30V) 2 2 Ammeter (0-10mA) 1 3 Resistors (^) 1k, 330, 220 1 each 4 Bread Board -- 1 5 Wires -- Required

Statement:

Superposition theorem states that in a linear bilateral network containing more than one source, the current flowing through the branch is equal to the algebraic sum of all the currents flowing through that branch when sources are considered one at a time and replacing other sources by their respective internal resistances.

Precautions:

1. Voltage control knob of RPS should be kept at minimum position
2. Current control knob of RPS should be kept at maximum position

Procedure:

1. Give the connections as per the diagram.
2. Set a particular voltage value using RPS 1 and RPS 2 & note down the ammeter reading
3. Set the same voltage as in circuit 1 using RPS 1 alone and disconnect RPS 2 and short circuit the terminals and note the ammeter reading.
4. Repeat the same procedure with RPS 2 and note down the ammeter reading.
5. Verify superposition theorem.
