A wire having high value of conductance is said to be:

1. Moderate conductor
2. Good conductor
3. Insulator
4. None of these

Correct answer: 2. Good conductor

The voltage required to create a flow of 0.3 C in 0.6 s through a resistance of 500 Ω is

The voltage required to create a flow of 0.3 C in 0.6 s through a resistance of 500 Ω is:

1. 100 V
2. 200 V
3. 250 V
4. 300 V

Correct answer: 3. 250 V

Solution:

Current (I) = Q/t = 0.3 C / 0.6 s = 0.5 A

Voltage (V) = IR = 0.5 A * 500 Ω = 250 V

The Electrical Engineering element that cannot be analyzed using Ohm’s law

The Electrical Engineering element that cannot be analyzed using Ohm’s law:

1. Resistance
2. Inductors
3. Capacitors
4. Transistors

Correct answer: 1. Transistors

Explanation: Ohm’s law doesn’t hold valid for unilateral networks since such networks only allow current flow in one direction. A transistor is a unilateral component and therefore Ohm’s law cannot be applied to Transistors.
