A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
The resistance used in a voltmeter is extremely high when measuring voltage, which is why the current is low (I = E/R).
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
A voltmeter measures the voltage present in the circut. Voltage is the amount of energy available to push charges through an electric circut.
The voltmeter function if the circuit is energized or the ohmeter function if looking for short or open circuits
To measure Voltage which is the force pushing current :)
for made of electric circuit safety device,
the purpose of a voltmeter is used to measure voltage in a circuit
the function of the control device is that you can know if the circuit is on or off
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
the function of a resister is to lower the voltage.
The function of a capacitor or an electric circuit is to store energy. It keeps this energy stored until it is need for release at a later time.
it's function is to supply energy(electric)
