shows voltage and current graphs for a capacitor.

a. What is the emf frequency ?

b. What is the value of the capacitance ?

(a) The emf frequency is .

(b) The value of the capacitance is .

We have been given that the voltage and current graphs for a capacitor in .

We need to find the emf frequency .

As the graph for voltage repeats after .

Therefore, the Time period is .

We know the formula, (Let this equation be ())

Substitute the value of T in equation (),

On simplifying,

We have been given that the voltage and current graphs for a capacitor in .

We need to find the the value of the capacitance .

Given values:

(from Part(a))

We know the formula, (Let this equation be ())

Divide both sides of equation () by ,

(Let this equation be ())

Substitute the values of in equation (),

On simplifying,
