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:
R = 56.6 ohms
Step-by-step 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
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{1.7}{0.03}\\R=56.6\ \Omega[/tex]
So, the resistance in the circuit is 56.6 ohms.
