AET Electrical Fundamentals 1

Question 1

What is the unit of electrical resistance?

Accepted Answer

Ohm

Answer

Resistance is measured in ohms (Ω), named after Georg Simon Ohm.

Question 2

According to Ohm's Law, if voltage is 24V and resistance is 6Ω, what is the current?

Accepted Answer

4A

Answer

Using Ohm's Law (I = V/R), 24V ÷ 6Ω = 4 amperes.

Question 3

Which type of circuit has all components connected end-to-end in a single path?

Accepted Answer

Series circuit

Answer

In a series circuit, current follows one continuous path through all components.

Question 4

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

Accepted Answer

It decreases

Answer

Adding resistors in parallel provides additional current paths, which decreases total resistance.

Question 5

What is the power consumed by a circuit with 2A of current and 12V applied?

Accepted Answer

24W

Answer

Power (P) = Voltage × Current = 12V × 2A = 24 watts.
