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)
Answer: Voltage = ____ volt

Answer:

V = 220 [V]

Step-by-step explanation:

In order to solve this problem we simply need to replace the given values of current and resistance in the expressions proposed.

R = 22 [kΩ] = 22000 [Ω]

I = 10 [mA] = 0.01 [A]

Voltage (V)


V = 0.01*22000\\V = 220 [V]\\
