Final answer:
Voltage describes the resistance to electrical flow and determines the force that drives current in a circuit.
Step-by-step explanation:
Voltage describes how much a material resists electrical flow. It is the difference in electric potential between two points in a circuit, which determines the force that drives the current. Voltage is measured in volts and is responsible for determining how fast current can flow in a circuit. It can be thought of as the electrical pressure that pushes the electrons through a circuit.
