What should power be applied to a 120V AC electrical circuit for?

To troubleshoot connections
Measure current and voltage
Test for insulation quality
Check circuit integrity

The correct answer is: Measure current and voltage

The application of power to a 120V AC electrical circuit for measuring current and voltage is fundamental for diagnosing the functioning of electrical components. When power is supplied, tools such as multimeters can be used to accurately measure voltage levels at various points in the circuit, helping to assess whether the voltage is within the expected range. Additionally, measuring current allows technicians to determine if the electrical load on the circuit is appropriate, identifying potential overloads or faults. This process is crucial because it enables a thorough understanding of how the circuit operates under normal conditions, which is essential for effective troubleshooting and repair. By confirming both voltage and current readings, a technician can get insights into the performance and safety of the system, ensuring it operates correctly within its design specifications.
