3. A traffic light has a total resistance of 22 k and requires 10 mA of current to
operate. What is the voltage required to operate the traffic light?
Given:
Resistance (R) = ______kΩ x (1 000Ω/1 kΩ) = _____Ω
Current (I) = ____ mA x (1 A /1000 MA = ____ A
Required: Voltage (V)
Solution:
V = I R
V = (_____ A) (______ Ω)
Answer:
Voltage = _______ volts
