Question

An iPod uses a standard 1.7 volt battery. How much resistance is in the circuit if it uses a current of

0.03 amps?

Answer 1

R = 56.6 ohms

Explanation:

Given that,

The voltage of the battery, V = 1.7 volt

We need to find the resistance in the circuit if it uses a current of 0.03 A.

Let the resistance be R. It can be solved using Ohms law as follows :

V = IR

`R=(V)/(I)\\\\R=(1.7)/(0.03)\\R=56.6\ \Omega`

So, the resistance in the circuit is 56.6 ohms.
