Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move perpendicular to the direction of the wave's travel.

Front

In a transverse wave moving from east to west, how do the particles of the medium move?

Back

The particles move north to south only.

Front

What is the formula to calculate current in an electrical circuit?

Back

Current (I) = Voltage (V) / Resistance (R)

Front

If a toy car has a resistance of 2 ohms and is connected to a 3 volt battery, what is the current flowing through the car?

Back

1.5 amps.

Front

What are the basic components of an electrical circuit?

Back

The basic components are a power source, load, and conductor.

Front

Which component is NOT a basic part of an electrical circuit?

Back

Fan.

Front

What does the law of attraction state?

Back

Like charges repel and opposite charges attract.

Front

What is direct current (DC)?

Back

Current that flows in only one direction.

Front

What is alternating current (AC)?

Back

Current that changes direction periodically.

Front

What is resistance in an electrical circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.
