Question

Define:

a) One coulomb(C)

b) One Ampere (A)

c) One volt (V)

d) One Ohm(Ω)

e) One Joule(J)

f) One Watt (W)​

Answer 1

a) One coulomb(C) : One Coulomb is equal to the charge transfer in a metal in one second while contantly 1 Ampere of current flows through it.

1 Coulomb = 1 Ampere × 1 second

b) One Ampere (A) : One Ampere is defined as the current that flows with electric charge of 1 Coulomb per second.

1 Ampere = 1 Coulomb / 1 Second

c) One volt (V) : One Volt is defined as energy consumption of 1 Joule per electric charge of 1 Coulomb.

1 Volt = 1 Joule / 1 Coulomb

d) One Ohm(Ω) : One Ohm is the resistance of a conductor such that when a potential difference of 1 Volt is applied to its ends,a current of 1 Ampere flows through it.

1 Ohm = 1 Volt / 1 Ampere

e) One Joule(J) : One Joule is equal to the energy transferred to (or work done on) an object when a force of 1 Newton acts on that object in the direction of its motion through a distance of 1 Metre.

1 Joule = 1 Newton × 1 Meter

f) One Watt (W) : One Watt is defined as the energy consumption rate of 1 Joule per second.

1 Watt = 1 Joule / 1 Second
