EIAT and NEIEP Test Electrical Theory

Question 1

What is the unit of electrical resistance?

Accepted Answer

Ohm

Answer

The ohm (Ω) is the standard unit of electrical resistance in the International System of Units.

Question 2

Ohm's Law states that voltage equals current multiplied by:

Accepted Answer

Resistance

Answer

Ohm's Law is expressed as V = I × R, where V is voltage, I is current, and R is resistance.

Question 3

In a series circuit, the total resistance is equal to:

Accepted Answer

The sum of all resistors

Answer

In a series circuit, resistances add directly: R_total = R1 + R2 + R3 + …

Question 4

Which type of current flows in one direction only?

Accepted Answer

Direct current (DC)

Answer

Direct current (DC) flows continuously in one direction, unlike AC which reverses direction periodically.

Question 5

What does a capacitor store?

Accepted Answer

Electrical charge

Answer

A capacitor stores electrical charge (and thus electrical potential energy) in an electric field between its plates.
