Real Power Versus Volts Times Amps
A watt meter reads real power, which takes the phase angle between voltage and current into account. With a heater or lamp the reading matches the voltmeter reading multiplied by the ammeter reading; with a motor or choke it comes out lower. That gap is a direct way to show students the difference between real and apparent power.
Meters That Work Alongside It
- Power Factor Meter 1ph — accounts for the gap between watts and volt-amperes.
- KWH Meter 1ph — adds power up over time as kilowatt-hours.
- Ampere Meter — AC ammeter for reading the load current.
The full set of electrical meters is in Lab Equipment.
