Fundamentals of Engineering Basic 3

Question 1

What does Ohm's Law state?

Accepted Answer

Voltage equals current multiplied by resistance

Answer

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

Question 2

Three resistors of 2 Ω, 3 Ω, and 5 Ω are connected in series. What is the total resistance?

Accepted Answer

10 Ω

Answer

Series resistances add directly: 2 + 3 + 5 = 10 Ω.

Question 3

Which material is classified as a semiconductor?

Accepted Answer

Silicon

Answer

Silicon is the most widely used semiconductor, having conductivity between conductors and insulators.

Question 4

What is the power consumed by a device drawing 2 A at 120 V?

Accepted Answer

240 W

Answer

Power P = IV = 2 A × 120 V = 240 W.

Question 5

In a parallel circuit, the voltage across each branch is:

Accepted Answer

Equal to the source voltage

Answer

In a parallel circuit, all branches share the same voltage as the source.
