Question

Which of the following is equal to the electric current flowing in an electric circuit?

• A. Speed with which a charge moves through a cross section area
• B. The force that acts on a charge
• C. Energy used to move a charge between two points
• D. Amount of charge that moves through a cross section area in unit time

Answer 1

The correct option is D Amount of charge that moves through a cross section area in unit time

The amount of electric charge flowing through a given cross section area of a conductor in unit time is equal to the electric current in the circuit.
$Electriccurrent=\frac{Electriccharge}{time}$$\Rightarrow I=\frac{Q}{t}$
