3. A traffic light has a total resistance of 22 kN and requires 10 mA of current to operate. What is the voltage required to operate the traffic light?
Given: Resistance (R) = KΩ × (1 000 Ω/1 K Ω) = Ω

Current (I) = mA × (1 A/ 1000 mA) = A

Required: Voltage(V)
Solution: V = IR
V = ( A) ( Ω)
Voltage = volt
