Question

Dimensional formula of resistance in physics with full solution

Answer 1

Answer:

Explanation:

Resistance:

The opposition to the flow of electric current is called resistance. It is represented by "R" and its unit is Ohm Ω

Resistance is given by the formula:

R = V / I   ........... (1)

where V is the voltage measured in volts 'V' and I is the current measured in amperes 'A'

We have to find the dimensional formula of resistance.

Since we know that,

Dimensional formula for V = M L² T ⁻³ A⁻¹

Dimensional formula for I = A

Put these values in equation (1), we get:

Dimensional formula for R = M L² T ⁻³ A⁻¹ / A

Dimensional formula for R = M L² T ⁻³ A⁻²

Hope it is helpful to you. Thanks.
