| Question | Answer |
| Components that are connected one after another on the same loop of the circuit are connected... | in series |
| The current that flows through each component connected in series is... | the same |
| If Christmas tree lights all go out when one bulb breaks what type of circuit is this? | Series Circuit. |
| What is a circuit? | Where current (electrons) flows through from a battery through a series of components, and back into the battery |
| What is current? | Flow of electrons |
| What is potential difference? | Potential difference (voltage) allows electricity to flow to make a current |
| Components that are connected on separate wires are connected in....... | Parallel. |
|

Both. |
| If you know the potential difference of a cell, how would you work out the total potential of a battery made up of these cells? | Add up the potential difference of each cell. |
| What is special about a thermistor? | Resistance decreases if temperature increases. |
| What is a battery? | Two or more cells connected together. |
| How do you find the total resistance of all the components in a series circuits? | Add up the individual resistances. |
| What is the definition of an electric current? | The rate of flow of charge. |
| What does Ohm’s law state? | Resistance is measured in ohms. The greater the number of ohms, the greater the resistance |
| What is the same at all points in a series circuit? | Current. |
| Calculating resistance, current and voltage (potential difference) | |
| How would you find the total current coming out of a cell in a parallel circuit? | Add up the currents in each branch of the circuit. |
