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].
