## PROBLEM # 2 - SOLUTION:

A CD Player with a resistance of 40 ohms has a
current of 0.1 amps flowing through it. How many volts supplies the
CD player?

Sketch:

Solution:

Start with the Equation of Ohm's Law

Since voltage is what needs to be found and the
equation is already interms of current and resistance, substitute in
the values for I and R.

Solve for Voltage (V).
