You will need a test instrument known as a clamp on amp meter. The test instrument clamps around one of the A/C units feed conductors. From the meter face you will read what the actual current is flowing through the feeder conductor.
Divide the power rating (in watts) by the voltage (in volts). So if you use a 100 watt light bulb in a typical 110 volt lamp then it will draw 100/110 = .91 amps of current. Or plug a 1500 watt electric heater into a 110 volt wall socket and it will draw 1500/110 = 13.6 amps of current.
No. If you connect two 12 volt batteries in series(positive to negative) to make 24 volts, you will have 100 amp hours. If you connect two 12 volt batteries in parallel(pos to pos, neg to neg) you will stay at 12 volts but have 200 amp hours
A volt-amp or VA is equivalent to watts, provided the voltage and amperage are in phase. So 1 kilo volt amp is the same as 1 kilowatt. Wattage, or power, is equal to volts times amps. So the original question is effectively nonsense. The number of amps depends on the voltage. If the voltage is 1000 volts, then there's 1 amp in 1 kilo volt amp. If the voltage is 1 volt, then there's 1000 amps. If there's 50 volts, then the amperage is 20 amps. And so on.
It's usually printed on the device, on the box, or in the manual. Voltage can be measured easily and with no risk with a volt meter, while amps are a bit more tricky.
Continuity tester, volt meter, clamp on amp meter, megger and ohm meter.
You can measure the electrical current with an amp meter. Amperage measures the current flow.
For AC circuits, amperage is checked with a clamp on amp meter. There is now in the market place a clamp on amp meter that will work on both AC and DC circuits.
There is no volt meter or amp meter in a DC watt meter.
Most volt/amp meters have a DC mode. You measure DC voltage by putting the two probes across the voltage source. You measure current by either putting the meter in series with the load or using a clamp on amp meter that measures current flow through induction.
test light or volt meter
No but you can use a volt meter to read voltage.
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
you dont you need an ammeter for that
Yes, you can hook up a clamp amp meter incorrectly, but it typically won't cause damage to the meter. If the meter is placed around the wrong conductor or if it is reversed, it may display a negative reading or zero current. Always ensure the clamp is positioned correctly around the conductor you intend to measure to obtain accurate readings.
Yes but the meter has to go in series with the load. There is a new clamp on amp meter being introduced, that will measure larger DC amperages without opening the circuit.
