Question

A cd player has a current of 0.1 a flowing through it. if the source voltage is 4v, what is the resistance? R=V/I

Answer 1

Given parameters:

Current of CD player = 0.1A

Source Voltage = 4V

Unknown:

Resistance = ?

Solution:

Based on Ohm's law;

V = I R;

V = voltage

I = current

R = resistance

Input the parameters and solve;

4 = 0.1 x R

R =
`(4)/(0.1)` = 40ohms

The resistance of the CD player is 40ohms
