Electrical circiuts
Question | Answer |
---|---|
Measures the current flowing through a circuit (current is the flow of electrons through a circuit) | Ammetre |
Measures volts. It can test to see if a battery is flat/or going flat (volts help push the current through a circuit) | Voltmetre |
When an appliance is turned on an eleric current flows. An elctric current is actually a flow of electrons (negativly charged particles found in atoms) | Current |
The higher the number of volts the more energy supply that is needed to drive the elecrtons around the circuit. e.g. different light globes. | Voltage |
Is the measure of how difficult it is for a current to move through a wire. | Resistance |
The unit for current is | Ampers (or amps) |
the symbol for current is | A |
The unit for voltage is | Volts |
The symbol for Volts are | V |
The unit for resistance is | Ohms |
The symbol for Resistance is | The grrek letter Omega |

This is a circuit is connect by more than 2 wires, and has 2 or more loads. | Parallel Circuit |
This circuit has only one wire connecting it | Series circuit |
......... is the flow of electrical charge around a circuit. | Current |
An ........ is used to measure this. | Ammetre |
A circuit which has only one path is called a ............... Circuit. | Series. |
A circiut which has 2 or more pathways is called a ............ circiut | Parrallel |
