Ham Radio Technician Test Basic Electronics & Circuitry 2

Question 1

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

Accepted Answer

It decreases below the smallest resistor

Answer

In a parallel circuit, total resistance is always less than the smallest individual resistor.

Question 2

Which component stores energy in an electric field?

Accepted Answer

Capacitor

Answer

A capacitor stores energy in the electric field between its plates.

Question 3

What is the unit of electrical capacitance?

Accepted Answer

Farad

Answer

The farad (F) is the SI unit of capacitance, named after Michael Faraday.

Question 4

In a DC circuit, if voltage doubles while resistance stays the same, what happens to current?

Accepted Answer

Current doubles

Answer

By Ohm's Law (I = V/R), doubling voltage with constant resistance doubles the current.

Question 5

What does a diode allow in a circuit?

Accepted Answer

Current to flow in one direction only

Answer

A diode is a one-way valve for current, allowing flow in only one direction (forward bias).
