Back

The glass rod becomes positively charged, and the silk becomes negatively charged.

Front

What type of charges repel each other?

Back

Negative and negative charges repel each other.

Front

Current measures how many electrons flow per second.

Front

What happens to the other bulbs in a circuit if one light bulb is removed?

Back

The other bulbs will stay on.

Front

How do you calculate voltage in a circuit?

Back

Voltage (V) = Current (I) x Resistance (R).

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charge to flow easily, while insulators do not.

Front

What is Ohm's Law?

Back

Ohm's Law states that V = I x R, where V is voltage, I is current, and R is resistance.

Front

What is the role of a battery in a circuit?

Back

A battery provides the voltage needed to push current through the circuit.
