in order for electric charge to flow, there must be a difference in: current. electric potential. resistance. static electricity.
Answer: electric potential
Explanation:
The flow of electric charges is known as electricity. Electricity flows from higher potential to lower potential. The difference in voltage/potential causes charges to flow. Potential difference is the amount of work done per unit charge to move against electric force. It measured in Volts = Joules/ Coulomb.
