1. Which of the following statements are true about electric current? List all that apply.
Electric current is measured in units of Amperes.
Electric current is equal to the number of Coulombs of charge which move past a point on a circuit per unit of time.
Electric current provides a measure of how fast charge moves between two points on a circuit.
The electric current in a circuit will increase as the electric potential impressed across a circuit is increased.
The electric current in a circuit will triple in value as the electric potential impressed across a circuit is increased by a factor of three.
Suppose a miniature light bulb is connected to a battery in a circuit. A light bulb with a greater resistance will have a greater current.
Wider conducting wires are capable of carrying larger currents
