# 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 .

See the step by step solution

## Part(a) Step 1: Given information

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

We need to find the emf frequency .

## Part(a) Step 2: Simplify

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,

## Part(b) Step 1: Given information

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

We need to find the the value of the capacitance .

## Part(b) Step 2: Simplify

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,
