Which component stores energy in a magnetic field?

Accepted Answer

Inductor

Answer

Inductors store energy in a magnetic field created by current flowing through a coil of wire.

Question 2

What does a multimeter measure?

Accepted Answer

Voltage, current, and resistance

Answer

A multimeter is a versatile instrument that can measure voltage (V), current (A), and resistance (Ω).

Question 3

What is the total voltage in a series circuit containing a 3V, 5V, and 7V source all aiding?

Accepted Answer

15 volts

Answer

In a series aiding configuration, voltages add together: 3 + 5 + 7 = 15 volts.

Question 4

What is the purpose of a ground in an electrical circuit?

Accepted Answer

Provide a common reference point and safety path

Answer

Ground provides a common voltage reference (0V) and a safe return path for fault currents.

Question 5

Which waveform is produced by a standard AC generator?

Accepted Answer

Sine wave

Answer

AC generators (alternators) naturally produce a smooth sinusoidal (sine wave) voltage output.
