QUESTIONS ABOUT ELECTRIC CIRCUITS

NAME: Nerea Luque Martín   GROUP:3º ESO A DATE: 26-4-17

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.
