voltmeter
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
Compute the open load voltage of the current source across its shunt resistance.This voltage becomes the voltage source's voltage.Move the current source's shunt resistance to the voltage source's series resistance.Insert the new voltage source into the original circuit in place of the current source.
Voltage is a measure of the E.M.F (electromotive force) which drives current around a circuit.
since it stands for voltage ohm meter :) can measure voltage current and resistance
current
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
The three ways to measure electricity in a circuit are voltage, current, and resistance. Voltage is the measure of electrical potential difference between two points, current is the flow of electric charge in a circuit, and resistance is the opposition to the flow of current.
A multimeter has the ability to measure both AC and DC current along with voltage and resistance.
Voltage divided by the resistance of what ever you want to measure the current in.
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
To measure high voltage use suitable instrument transformer (potential transformer) Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.
