The easiest method today is by using a clamp meter. It "clamps" around a single conductor and measures the magnetic field (you can't get a reading by clamping around a regular appliance cord, as both conductors will cancel each other out).
The unit of measure for current load is amperage, or simply amps.
Amperage.
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
To measure amperage output to see if an alternator is charging or not .
An ammeter measures amperage not voltage.
Electrical current stated or displayed as Amperage
With kitchen tongs. A mild tingling indicates low voltage/low amperage. Muscular spasms indicate high voltage/low amperage. Unconsciousness sans death indicates low voltage/moderate amperage. Death indicates high amperage. Good luck.
To determine this you will have to measure the amperage the starter draws when you crank the engine. This amperage times the voltage (12 volts) will give you the wattage. There are 746 watts to 1 HP.
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
The current is the amperage. It is measured in series. Voltage is measured across the line (parallel).
Measures the amperage of the current .Your battery is in series with your car amp meter .
You can measure the electrical current with an amp meter. Amperage measures the current flow.
