Question

find out the dimensional formulae of the following charge,electric potential,resistence​

Answer 1

The dimensional formulae of charge, electric potential and resistance is as follows:

• The electric current can be found out by using the formula:

q = I*t

Where q = charge

I = current

t = time

Therefore the dimensional formula will be  [M⁰L⁰T¹I¹].

• We know that E = qV

Where E = Potential energy

q = charge

V = electric potential

V = E/ q

The dimensional formula of any kind of energy is [M¹L²T⁻²]

The dimensional formula of electric charge= [M⁰L⁰T¹I¹]

Therefore the dimensional formula of electric potential V = [M¹L²T⁻³I⁻¹]

• Resistance = Voltage*Current⁻¹

Voltage = [M¹L²T⁻³I⁻¹]

Current = [M⁰L⁰T⁰I]

Therefore dimensional formula of resistance = [M¹L²T⁻³I⁻²].
