  1. Solve the following problems using the formulas of Ohm's Lew.

Model.-- Current equals 5 amp; resistance equals 10 ohms. How much is the voltage?

— Voltage equals current times resistance. 5 x 10 -50 V

I) R = 80 ohms

2) R - 10.25 ohms

3) V = 50.05 V

V -55 V

I = 35 amp

I - 120 amp

I = ?

V - ?

R = ?

4) I = 10,500 amp V -2,000 V

R = 2

5) V -20.05 V

R -0.015 ohm I = ?

6) I = 0.24 amp

R = 1.36 ohms V = ?
