Electrical Circuits Quiz

Potential Difference is defined as...

• The amount of charge flowing through a circuit per unit time.

• The amount of charge per electron.

• The amount of energy per unit charge.

• The amount of energy per unit time.

In what direction does "Conventional Current" flow in a circuit?

• From positive to negative.

• From negative to positive.

• Current doesn't flow in a circuit... it just stays still.
