PSU 0-20V d.c variable

Project Board, pp272, 500 mA

Millimater d.c 0-100mA

Voltmeter dc 0-20V

Description:

Voltage of a resistor is directly proportional to its current. Resistors can show a tolerance which is stated on it.

- Experiment 2: NETWORKS
### Experiment 2: NETWORKS

Objective:

To investigate what happens when resistors are interconnected in a circuit.

Apparatus:

PSU 0 - 20V d.c variable

Project Board, pp272, 500 mA

Milliameter d.c 0 - 100 mA

Voltmeter dc 0-20V

Description:

According to the Kirchhoff’s current law, the algebraic sum of all currents at any junction is zero. According to the Kirchhoff’s voltage law, in a closed circuit, the algebraic sum of the voltages around the circuit is zero.

- Experiment 3: SUPERPOSITION
### Experiment 3: SUPERPOSITION

Objective:

To investigate the effects of more than one voltage source in a network.

Apparatus:

PSU 0-20V d.c variable
