| Questão | Responda |
| What is electrical charge? | The flow of electrons/current |
| What is potential difference? | Energy transferred per coulomb of charge passing through a component |
| Give the unit for charge | Coulombs, C |
| Give the unit for power | Watts, W |
| Give the unit for current | Amps, A |
| Give the unit for resistance | Ohms, Ω |
| How is potential difference shown in series and parallel circuits? | Series: Potential difference is shared between components Parallel: Potential difference is the same through each component |
| How is current shown in series and parallel circuits? | Series: Current is the same throughout the circuit Parallel: Current is different in different branches |
| Why does a current-potential difference graph for a diode stay at 0 for negative readings? | Diodes only allow current to flow in one direction |
| Describe a current-potential difference graph for a resistor | A straight, linear line for both positive and negative readings |
| Describe a current-potential difference graph for a lamp | A slanted S shape |
