Front

What is the unit of measurement for voltage?

Back

Volts (V)

Front

What happens to an object when it loses electrons?

Back

It becomes positively charged.

Front

What is the electrical symbol for one battery?

Back

A long line (positive terminal) and a short line (negative terminal) in a series.

Front

What is a material that allows electrons to move easily called?

Back

Conductor.

Front

How does the length of a wire affect its resistance?

Back

Longer wire increases resistance.

Front

What is the unit of measurement for current?

Back

Amperes (A) or Amps.

Front

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

Back

Ohm's Law: V = I × R.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily.

Front

What is the effect of increasing voltage in a circuit?

Back

It increases the current if resistance remains constant.

Front

What is static electricity?

Back

The buildup of electric charge on the surface of objects.
