65 street lights are fed by a 2275-volt series circuit. What is the voltage across each light?

• A. 25 V
• B. 30 V
• C. 35 V
• D. 40 V

Answer: (C)

To determine the voltage across each light in a series circuit, you need to divide the total voltage by the number of lights in the circuit. Here, you have 65 street lights and the total voltage feeding them is 2275 volts.

To find the voltage across each light, the calculation is as follows:

Voltage per light = Total Voltage / Number of Lights

Voltage per light = 2275 V / 65

Calculating this gives you:

Voltage per light ≈ 35 V

Therefore, each street light receives approximately 35 volts. This reflects the fundamental principle of a series circuit where the total voltage is evenly distributed among all components. Since there are 65 lights receiving the total voltage, dividing the total by the number of lights yields the voltage across each individual light, confirming that 35 volts is indeed the correct answer.
