State an equation linking Current, Charge and Time, including units
Charge flow (Coulomb)= Current(Amperes) X Time (seconds)
2 of 7
What is meant by potential difference and resistance of a circuit?
Potential difference (voltage) is the electronic force and resistance is the opposition to the flow.
3 of 7
What is the equation linking potential difference, current and resistance, including units?
Potential difference (Voltage) = Current (Amperes) X Resistance (Ohms)

How would you investigate the link between length of wire and resistance?
Create a series circuit with an Ammeter recording current and a voltmeter measuring voltage. Put the wire against a ruler and put connected crocodile clips at different lengths of the wire to record different resistances.

How can the resistance of LDRs and Thermistors be altered?
The resistance of thermistors decrease as the temperature increases. The resistance of LDR's decrease as light density increases.
