A resistor is connected across an oscillating emf. The peak current through the resistor is** ** What is the peak current if:

**a.** The resistance is doubled?

**b**. The peak emf is doubled?

**c.** The frequency is doubled?

(a.)

(b.)

(c.)

We are given that A resistor is connected across an oscillating emf. The peak current through the Resistor is ** .**

And we need to find that What is the peak current if resistance is doubled?** **

In this q we have to find what is the value of max current in circuit while changing the value of

It is based on RLC circuit

We know that ,

The maximum current of RLC circuit is

Now we see that I is directly Proportional to and inversely proportional to

So ,

a). If is doubled then will be halved of present value so

Hence final answers of a) is
