Question

Do volts measure the flow of an electric current through a circuit?

Answer 1

No Its amps

Answer 2

Amperage is the current flowing through a circuit or portion of a circuit. Voltage is the electromotive force (EMF) applied to the circuit and can be likened to pressure.   Apply more EMF to a resistance and you can force more electrons to flow through that resistance. Flowing electrons make up what is known as current which is measured in amps.  This relationship between voltage resistance and current is expressed in Ohms law which states.

Voltage = Current x Resistance

Voltage can indirectly measure amperage. By using Ohms law it is possible to measure a voltage across a known resistor and compute the current flow.

Answer 3

No. Current is measured in amperes. The equation is E= I/R, where E is current, I is volts, and R is resistance, measured in ohms.

Volts indicate the 'pressure' analagous to pressure in a hose.

Answer 4

No, amperage (current) measures the flow of electricity. Voltage measures the difference in potential electrical energy between two points.
