using voltmeter

[hashimaba]

What will happen if we use a voltmeter to measure current in a circuit. I mean if we connect our voltmeter leads at different points on current carraying wire/coil?

To measure current with a multimeter you need to connect it in series with the load your measuring. Be aware most multimeters have different sockets to connect your leads into for measuring current and they are normally limited to about 10 amps. Get a clampmeter its far easier.

Voltmeters only measure voltage (the potential difference between each probe.)

The diffence with an ampmeter is that you are basically placing a low value shunt resistor in series with the load, and the voltage across the resistor is measured by the meter.
This is why you have different connectors for volts & amps on multimeters.

If you measure across a circuit (as you do for voltage) while the mulitmeter is set for amps then it is the equivalent of placing the shunt resistor across the supply.
So make sure your meter is properly fused

As Steve1412 says a clampmeter is far easier and will also measure higher current ranges.
Plus its better to have seperate volt and amp meters to prevent you soiling your pants
