Sample Problem 4
What voltage or potential difference is used by an electrical
appliance that draws 0.4 amps of current and has a resistance of
3 ohms?
Given:
R = 3 Ω
V = ?
I = 0.4 A
Solution:
V = I R
V = ( 0.4)(3)
V = 1.2V
The voltage or potential difference is used by an electrical
appliance is 1.2 V.
