b. What is the resistance of the light bulb?
a. What is the voltage across the light bulb?
b. What is the resistance of the light bulb?
Answers
power in watts = Volts * current in amps
60 = V * 0.5
V = 120 Volts (seems about right)
V = i R
R = V/i
60 = V * 0.5
V = 120 Volts (seems about right)
V = i R
R = V/i
