A; By using a voltmeter across a small shunt resistor
What else can I help you with?
A scientist measuring current will get a measurement in?
Amps
After using current how many voltage and amps will be in return line?
The amps will be the same. Volts will depend on between which two points you're measuring it.
What is the unit for measuring electric current called?
The unit for electrical current is the ampere.
Ammeter is a device used for measuring?
Measures current, both AC or DC, usually in Amps.
How do you calculate 1 phase kWh from measuring amps on each phase?
Measuring the current in each phase (or do you mean 'line'?) will not give you sufficient information to work out what you are asking for.
What is a current measured in?
Ammeters (amps) An Ammeter is a meter for measuring electrical current, the unit of which is the Ampere (amp)
How do you calculate 1 phase kwh from measuring amps?
You can't. Measure the amperes simply tells you what the current is.
How many watts does 100 amps at 120 v?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
What is the unit for measuring voltage?
Volts is the unit measurement for voltage Current is amperes or amps for short Resistance is ohms
Why do you register 2 amps on an electrical meter?
Registering 2 amps on an electrical meter could indicate that there are two separate circuits drawing 1 amp each, or it could mean that there is a single circuit with a total load of 2 amps. The meter simply sums up the current flowing through each circuit it is measuring.
What do you use a clamp meter for?
The clamp part is for measuring amps via induction. You set meter to amps and clamp around only a single wire. Device you are measuring must be operating. This means you couldn't clamp around a lamp cord to a table lamp since the current induced in each direction cancels out. You would have to separate the wires. An electrician would carry a short extension cord with the wires already separated. Most often a clamp meter is use to checks amps in a breaker panel on the black wire coming from the breaker.
How does a ammeter?
An ammeter works by measuring the voltage across a very small resistor that is placed in series with the load. By Ohm's Law, current is voltage divided by resistance. Knowing the resistance of the series circuit and conducting those amps to a device that reacts differently with varying amount of amps you can accurately measure the amps of a circuit. Analogue meters use an electromagnetic coil that winds itself to different tensions depending on the amount of current. Connect it to a needle and put a chart behind it that has been calibrated to the coil and you have created a device for measuring current. The strength of the electromagnetic field is proportional to the current, or amps, so the distance the needle moves will also be proportional to the current.
