Units

Question 1

What unit measures the amount of electric charge?

Answer 1

Coulomb (C) The Coulomb is the SI unit of electric charge. One Coulomb represents the charge transported by one ampere of current in one second.

Question 2

What unit measures the rate of flow of electric current?

Answer 2

Ampere (A) The Ampere is the SI unit of electric current, representing one Coulomb of charge flow per second.

Question 3

Which unit represents electric potential or voltage?

Answer 3

Volt (V) The Volt is the unit of electric potential or electromotive force. It measures the potential difference across a conductor when one ampere of current dissipates one watt of power.

Question 4

What unit measures the rate at which work is done or energy is transferred?

Answer 4

Watt (W) The Watt is the SI unit of power, representing one joule of energy transferred or converted per second.
