Sample Problem:
How much current flows through a lamp with a resistance of 60 ohms when the voltage across the lamp is 12-V?
G: R = 60 ohms
V = 12 volts
R: I = ?
E: I = VR
S: I = 12 volts
60 ohms
A: I = 0.2 Amperes
1. Use GRESA Method to solve for the amount of current that will flow in a lamp with a resistance of 40 ohms when the voltage across the lamp is 15 V.
