Dimensional Formula of Charge
The dimensional formula of charge is given by,
M0Â L0Â T1Â I1
Where,
- M = Mass
- I = Current
- L = Length
- T = Time
Derivation
Electric Charge (Q) = Electric Current × Time . . . . (1)
The dimensional formula of Current and Time is [M0 L0 T0 I1] and [M0 L0 T1] respectively . . . . (2)
On substituting equation (2) in equation (1) we get,
Electric Charge = Electric Current × Time
Or, Q = [M0 L0 T1Â I1]
Therefore, the charge is dimensionally represented as [M0 L0 T1Â I1].
