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

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

- Moderate conductor
- Good conductor
- Insulator
- 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:

- 100 V
- 200 V
- 250 V
- 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

## Unit of electrical charge in SI system is

SI Unit of electrical charge is:

- Newton
- Coulomb
- Tesla
- Watts

Correct answer: 2. Coulomb

## The Form factor for DC supply voltage is

The Form factor for DC supply voltage is:

- Zero
- Between 5 to 10
- Infinity
- Unity

Correct answer: 4. Unity

Find brief explanation for above

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

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

- Resistance
- Inductors
- Capacitors
- 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.
