EIAT and NEIEP Test FREE NEIEP Electrical Theory Questions and Answers

Question 1

What does Ohm's Law state?

Accepted Answer

Voltage equals current multiplied by resistance (V = IR)

Answer

Ohm's Law states V = IR, meaning voltage (V) equals current (I) times resistance (R).

Question 2

What is the unit of electrical current?

Accepted Answer

Ampere

Answer

Electrical current is measured in amperes (amps), named after physicist André-Marie Ampère.

Question 3

In a series circuit with three resistors of 4Ω, 6Ω, and 10Ω, what is the total resistance?

Accepted Answer

20Ω

Answer

In a series circuit, total resistance = sum of all resistors = 4 + 6 + 10 = 20Ω.

Question 4

What happens to total resistance when resistors are connected in parallel?

Accepted Answer

Total resistance decreases

Answer

Parallel resistors provide multiple current paths, reducing total resistance below the smallest individual resistor.

Question 5

Which material is the best conductor of electricity among common wiring metals?

Accepted Answer

Copper

Answer

Copper is one of the best electrical conductors among common materials, which is why it is widely used for wiring.
