What is the equivalent value of 120 kV in volts?

• A. 12,000 V
• B. 120,000 V
• C. 1,200 V
• D. 120 V

Answer: (B)

The value of kilovolts (kV) is a measurement of electrical potential, where 1 kV equals 1,000 volts. Therefore, when converting 120 kV to volts, you multiply 120 by 1,000. This results in 120,000 volts.

Understanding the conversion from kilovolts to volts is crucial, especially in fields such as electrical engineering and apprenticeships in electrical work, since measurements at higher voltages often require precise understanding and application. In this situation, recognizing the basic unit conversion allowed you to identify that 120 kV corresponds directly to 120,000 volts, making it clear why this choice is the correct answer.
