What does voltage describe?
a. how fast current can flow
b. how much current can flow
c. how much a material resists electrical flow
d. how fast a material conducts electrical flow

Answer;

B. How much current can flow

Explanation;Voltage is the measure of potential difference between two points of a circuit, it is this potential difference that causes the movement of electric charges in a circuit. voltage acts as a force that pushes electric charges making them to flow through the conductor.Voltage is therefore the measure of how much current can flow in a given circuit or a conductor. Voltage is measured in volts measured using a device known as voltmeter.
