Assignment

1. Apply Norton’s theorem to the circuit shown to determine the current through the resistor R4.

2. Use Norton’s theorem on the circuit shown to determine the voltage across the resistor R4.

3. For the circuit given, use Norton’s theorem to determine the current through the resistor R5, when R1 is open circuited.

4. For the circuit given, use Norton’s theorem to determine the current through the resistor R5, when R1 is open circuited.

5. Use Norton’s theorem to determine the new value of R1 in the figure that will give I1 = 0.4 mA.
