Find the dimensional formulae of
a the charge Q.
the potential V,
c. the capacitance C and
d the resistance R.
Some of the equations containing these quantities are `
`Q=It, U=VIt, Q=CV and V=RI,`
where I denotes the electric current, t is time and U is energy.

Explanation

To find the dimensional formulas for charge \( Q \), potential \( V \), capacitance \( C \), and resistance \( R \), we can use the provided equations and the known dimensional formulas for fundamental quantities.

### Step-by-Step Solution:

1. **Finding the Dimensional Formula for Charge \( Q \)**:
- We use the equation \( Q = It \), where \( I \) is electric current and \( t \) is time.
- The dimensional formula for electric current \( I \) is denoted as \( A \) (Ampere).
- The dimensional formula for time \( t \) is \( T \).
