Unit 3: Electricity and Magnetism Test

Front

What are the two types of circuits?

Back

Series and parallel.

Front

What is the method of charge transfer when walking across a carpet?

Back

Friction.

Front

In a series circuit with 3 light bulbs, if 2 are removed, what happens to the brightness of the remaining bulb?

Back

The remaining bulb will be brighter.

Front

What do positive electric charges do to other positive charges and negative charges?

Back

They repel positive charges and attract negative charges.

Front

What is the relationship between voltage, current, and resistance called?

Back

Ohm's Law.

Front

Define a series circuit.

Back

A circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

Define a parallel circuit.

Back

A circuit in which components are connected across common points or junctions, providing multiple paths for the current.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases.

Front

What is the formula for Ohm's Law?

Back

V = I × R, where V is voltage, I is current, and R is resistance.
