Define 1 ohm,1 volt, 1 ampere briefly?



One Ohm is described as the resistance of a conductor with a potential difference of one volt applied to the ends via which one ampere current flows.

Electrical resistance SI unit is Ohms

Ohm (Ω) = One volt (V)/One ampere (1A)

1 A = 1 V/Ω

Potential difference

Potential difference is defined as the amount of work done in moving unit positive charge from one point to another.

The unit of potential difference is volt(V).

One Volt = One Joule (J) /Coulomb(C)


An Ampere can be defined as the unit of electric current that is equal to the flow of one Coulomb per second. One ampere of current represents one coulomb of electrical charge, i.e. 6.24×1018 charge carriers, moving in one second.

1 Ampere = One Columb (C)/One second (S)
