Question

1. what causes electrons to flow through an electrical circuit? select all that apply.

resistance
potential difference
voltage
insulation

Explanation:

• Resistance opposes electron flow, not causes it.
• Potential difference is the driving force for electron flow in a circuit.
• Voltage is another term for potential difference, so it also causes electron flow.
• Insulation prevents electron flow, it does not cause it.

Answer:

• potential difference
• voltage
