The unit of current is the ampere (A), or amp for short. A thousandth of an amp is a milliamp (mA). One amp is equal to one coulomb of charge per second.

Should current be measured with the power off the circuit?
It will not be possible to measure current unless the circuit is powered and operating.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What measures the flowing in a circuit?
The flow in a circuit is called the electric current and it is measured by voltages. The number of volts that are present in the charge will determine the strength of the electric current.
The total opposition to current in a series RC circuit is called?
Assuming you are talking about an AC circuit, then the total opposition to the flow of current in an R-C circuit is called its impedance (symbol: Z), measured in ohms. This is the vector sum of the circuit's resistance (R) and its capacitive reactance (XC) -each also measured in ohms.
How do you measure current - both magnitude and phase in ac circuit with reactive elements?
This is most easily done using an oscilloscope with a current probe. Also phase angle must be measured relative to something else, usually the AC voltage at one end or the other of the branch of the circuit where the current is being measured.
How to measure current?
Current in a circuit can be measured by using a device called ammeter that is always connected in series in the circuit in which current is to be measured.
The current in a circuit is measured in?
Amperes
What is the current flowing in a circuit measured in?
amperes or A.
Should current be measured with the power off the circuit?
It will not be possible to measure current unless the circuit is powered and operating.
What does a ammeter do in a circuit?
An ammeter measured how many amperes of current are flowing in an electrical circuit.
How is current measured in a series circuit?
Current is measured in a series circuit by the use of a multimeter. First, the power source must be attached to the circuit board. The board is attached to the multimeter, then that is attached back to the power source.AnswerCurrent is measured either with an ammeter, or with a multimeter set to measure current. The instrument must be connected in series with the other components in the circuit.
What is meaured in amps?
The electrical current in a circuit is measured in amps.
How does the voltage across a load is measured in a circuit with alternating current?
It's measured with an AC voltmeter.
What are the direct current instruments and measurements?
D.c GeneratorComputers=======================DC voltage is measured with a voltmeter.DC current is measured with an ammeter.That's all there is to measure in a DC circuit.
How is a parallel circuit the same as a series circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
Is a series circuit the same as a parallel circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.

The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
