How is resistance related to the flow of current in a circuit?

• Resistance causes the flow of current in a circuit to stop completely.

• Resistance has no effect on the flow of current in a circuit.

• Resistance is directly proportional to the flow of current in a circuit.

• Resistance is inversely related to the flow of current in a circuit.

At which point is the electric field the weakest?

• because it is the furthest away

• because the field lines are further apart

• because the field lines are further apart

•  because it is the furthest away
