8. What is Resistance
- A measure of the rate of energy transfer.
- A measurement of the flowcharge in a circuit.
- A measure of how difficult it is for current to pass through a wire.
- A measure of the current passing through a wire.
9. What is the value of a giga-amp (GA)

10. How is resistance caused
- A change in length in the wire
- Caused by the kinetic energy of the particles decreasing
- Caused by the collisions of the charge carriers with each other
- Caused by the current through the wire being halved.
