4. define voltage and explain its role in a circuit.\nopposition to flow; it limits current\nelectrical pressure; it pushes current through the circuit\nrate of energy use; it calculates power\nthe flow of electrons; it measures resistance

Answer

Brief Explanations:

  • The first option describes resistance, not voltage.
  • The second option correctly defines voltage as electrical pressure, which provides the driving force to push electric current through a circuit.
  • The third option refers to power, not voltage.
  • The fourth option describes electric current, not voltage.

Answer:

Electrical pressure; it pushes current through the circuit
