Your meter might be jumping because you are using a lot of electricity. This could be because you are washing or drying clothes, or even using the air conditioning system. Also, using computers a lot uses a lot of electricity, which may cause the amperage on the meter to jump.
Your main breaker should tell you the amps of your panel.
a ten-wrap amperage multiplier is used with a (n)
Wire is sized by the amperage that it will carry. 5 kW is 5000 watts. The equation to find watts is W = Amps x Volts. The equation to find amps is Amps = Watts/Volts. As you can see a voltage is needed to calculate the amperage. Once the amperage is stated, the wire size can be given for that particular amperage.
There are zero watts in 220 volts. Watts are the product of amps x volts. To receive an answer, the amperage of the device has to be stated. This amperage multiplied by the stated voltage will give you the wattage of a device.
The formula for amps is I = W/E. Amps = 40/240 = .17 primary amperage. For the secondary amperage I = W/E. Amps = 40/24 = 1.7 amps.
Your main breaker should tell you the amps of your panel.
If the appliance tells you how many watts it's supposed to use you can buy a watt-meter to measure how many watts the appliance is using buy plugging in the meter into the wall and then plugging the appliance into the meter. A popular brand is "Kill A Watt", it meter can be bought on E-bay for under $25.
You can measure the electrical current with an amp meter. Amperage measures the current flow.
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.
1 meter
Turn off circuit. Then you can use a meter set for resistance, clip onto both ends of the resistor, meter will display the resistance in ohms.If you know the voltage and amperage you can use Ohm's Law: E=IRR=E/IR is resistance, E is voltage, and I is current (amperage)
Measures the amperage of the current .Your battery is in series with your car amp meter .
To measure very low amperage a milli amp meter would be used or the milli amp scale on a multi meter.
no, usually increase the rpm of your car, this will kick in the generator - this will supply amperage to start other car
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.
