PHY301-Circuit Theory Assignment #Questions

Q: 1:

Find the total resistance between the positive and negative terminal of the battery also calculate current of the equivalent circuit. Draw and label the circuit diagram of each step, otherwise you will lose your marks. Write each step of calculation to get maximum marks

Q: 2:

Consider the circuit arrangement shown in fig. below.

(1)   Find the current I through the network.

(2)   Calculate the current through each resistor

(3)   Calculate the power dissipated across resistance R1

(Note: mention the unit of each derived quantity)

Q: 3:

Given below is a simple circuit containing battery, bulbs and two switches.

Describe the current flow in the circuit and bulb (glow or not) for each given condition

1. When switch 1is ON and switch 2 is OFF.
2. When both switches are ON.
3. When switch 1 is ON and switch 2 is directly connected without bulb (short)
