1. What kind of energy does a cell store?
-Chemical energy.
2. What do you call it when two or more cells are connected?
-Battery
3. Could you write a definition of electric current?
-Is a flow of microscopic particles called electrons flowing through wires and components.
4. In which direction does the electricity flow in a circuit?
-From the negative terminal to the positive terminal of a cell.
5. What are the components of an electric circuit?
-Cell, lamps, wires and switch.
6. What happens if there is a break in a circuit?
-The current could not flow.
7. Could you draw 10 electric symbols and write their names? 
8. Could you write two characteristics of serial circuits?
- The components are connected end-to-end, one after the other.
They make a simple loop for the current to flow round.
9. Could you write two characteristics of parallel circuits?
-The components are connected side by side.
The current have a choice of routes.
10. What unit is electrical current measured in?
-Is measured in amp (A) using an ammeter.
11. What is the electrical push that the cell gives to the current in a circuit?
- Is called the voltage. It is measured in volts (V) on a voltmeter.
12. What device is used to measure electric current?
-Is called ammeter
13. What device is used to measure voltage?
-Is called voltmeter.
14. Are ammeters and voltmeters connected in a circuit in the same way?
-No, unlike an ammeter a voltmeter is connected across the components.
15. Give me a synonym for voltage.
-Potential difference (pd)
16. What happens to the voltage in a series circuit?
-Voltage is shared between the components.
