How to Evaluate Voltmeter current?

Voltmeter current evaluator uses Current Magnitude = (Voltmeter Range-Resistance)/Voltmeter Resistance to evaluate the Current Magnitude, The Voltmeter current formula is defined as is an instrument used for measuring the electrical potential difference between two points in an electric circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current. Current Magnitude is denoted by I symbol.

How to evaluate Voltmeter current using this online evaluator? To use this online evaluator for Voltmeter current, enter Voltmeter Range (V_r), Resistance (R) & Voltmeter Resistance (R_v) and hit the calculate button.

FAQs on Voltmeter current

What is the formula to find Voltmeter current?
