Voltmeter

A voltmeter is an instrument that serves to measure the electrical voltage. With the added multiplier tool will be able to improve the ability of the voltmeter measurement tool many times over.

Magnetic force will arise from the interaction between magnetic fields and strong currents. Magnetic style will be able to make a voltmeter gauge needle move when there is an electric current. The greater the electric current, the greater the deviation mengelir needle happens.
