I think you mean 'alternating' current ('alternative' means choice). The ammeter must be inserted in series with the load, just as with direct current.

Why is voltmeter is connected in parallel and ammeter in series?

Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.


How do you measure the current through a circuit without intercepting the supply?

Add an ammeter in parralel with the circuit. An ammeter in parallel with a circuit to be measured will not measure any current. In fact, placing an ammeter in parallel will cause a short. The ammeter must be placed in series with the circuit to be measured. It should be noted that this technique only allows for small magnitudes of current to be measured. One should not try to measure more than 10 amps using this method. However, this is not the goal of the question asked. I am not 100% sure what "intercepting the supply" means but I think the person asking the question means without breaking the circuit? In this case one could use a clamp on ammeter. There are several varieties that can measure low currents and there are those that can measure 100s of amps.


How do you measure electrical current?

Electric current is measured using an instrument called an ammeter. The SI unit of measurement for current is the ampere, which is defined in terms of the force between parallel, current-carrying, conductors due to the interaction of their magnetic fields.


How do you measure the resistance of a motor?

we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance


What is ammeter selector switch?

A selector switch is normally used in a place to avoid 3 ammeters usage and instead measuring current in all the 3 phases using 1 ammeter only. Motto: SAVE MONEY.. :D The selector switch provided for ammeter is to check the amount of current taken from each phase supply. (ie) R,Y and B. Each phase supply should be covered with a current transformer with the rated amps capacities. The two leads of the the each phase CT are connected to the respective leads in the selector switch of the ammeter.

How do you measure the value of the amplitude of an electric current?

The value of the amplitude of an electric current is measured in amperes (A) using a tool called an ammeter. The ammeter is connected in series with the circuit to measure the flow of current. The reading on the ammeter displays the amplitude value of the current.

ammeter, which is understood as an amp meter


How is the strength of electric current measured with?

The strength of an electric current is measured in amperes (A) using an ammeter. An ammeter is a device that is connected in series in a circuit to measure the flow of current. The higher the current flowing through a circuit, the higher the amperage reading on the ammeter.


What is the current and how is it measured in electrical circuits?

The current in electrical circuits is the flow of electric charge. It is measured in amperes (A) using a device called an ammeter. The ammeter is connected in series with the circuit to measure the current passing through it.


How do you measure voltage using a ammeter?

An ammeter measures amperage not voltage.


The unit of current?

What is a measure of current flow?

Current flow is typically measured in amperes (A), which represents the rate of flow of electric charge through a circuit. It can be measured using an ammeter, which is connected in series within the circuit to measure the current passing through.


What do you use to measure an electric current?

An ammeter, either shunt or inductive. A shunt is an inline resistor of a small, known resistance. Knowing the resistance and the voltage one can calculate the amperage by Ohms law, I=V/R. An inductive, or clamp on ammeter measures the magnetic field and using more complex calculations displays the current, typically on a digital display.

Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.


List two important things to remember when using an ammeter?

Make sure it is placed in the circut series so you can measure the electrical current at a specific point.
