13.1 Flow of Electricity

The bulb will light up.

• True

• False

(Definition)

An electric current is the

• flow of electricity

• flow of electric charge

• rate of flow of electric charge

• conventional current

The SI unit of current is the

• volt ( V ) 

• ohm ( $\Omega$ )

• ampere ( A )

In a closed electric circuit, current flows from

• the negative terminal of a battery to the positive terminal

• the positive terminal of a battery to the negative terminal

In a closed electric circuit, the electron flow

• occurs from the negative terminal of a battery to the positive terminal

• occurs from the positive terminal of a battery to the negative terminal

The potential difference (or p.d.) between any two points is the

• amount of energy needed to move one unit of electric current from one point to another.

• amount of energy needed to move one unit of electric charge from one point to another.

The SI unit of potential difference is the

• volt ( V ) 

• ohm ( $\Omega$ )

• ampere ( A )
