How It Is Used
The current coil is wired in series with the load through C1–C2 and the voltage coil across it through P1–P2. The pointer then shows real power, the product of voltage, current and power factor, so students can compare resistive and reactive loads and study power factor on the bench.
Frequently Asked Questions
How is the Portable Analog Wattmeter connected?
