Question

Define 1 volt and electric current

Answer 1

One volt is defined as energy consumption of one joule per electric charge of one coulomb. 1V = 1J/C. One volt is equal to current of 1 amp times resistance of 1 ohm. 1V = 1A * 1Ω Collection of one Columb charge on unit farad capacitor is one volt.

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. Electric charge is carried by charged particles, so an electric current is a flow of charged particles.

Answer 2

ELECTRIC CURRENT

• This flow of charges in the metal wire constitutes an electric current

• It is the potential difference between the ends of the wire which makes the electric charge to flow in the wire..

volt

• The S I unit of potential difference is volt
