Electricity Flashcards
In a battery sign, how is it different to a cell sign
Because it has a dotted line and has two sets of the sign
In the cell sign, which lines the longest
The positive (plus) side
What does then lamp sign look like
It’s a circle with a cross in the middle
What’s the use for a cell
To give energy to the circuit
What’s the use for a battery of cells
To give energy to electricity to the circuit
What’s the use for a lamp
To light up when electricity is introduced to it
What’s the use for a switch
To switch the lamp on and off
What’s the use for an ammeter
To measure how much current is following round the circuit. It measures in amps
What is the use for a voltmeter
To measure the amount of push at different parts in the circuit. It measures in volts
What is the independent variable
What we will change eg. Bulbs
What is a dependant variable
What you measure in eg. Volts, amps
What is a control variable
Something that you keep the same
What’s the name of the circuit with one route
Series
What’s the name of the circuit with two paths
Parallel

No
……………. is two or more cells together
Battery
A …………………. can be used to reduce the current in a circuit
Resister
Something that will let electricity flow through it is a ……………….
Conductor
Bulbs, cells and switches are all circuit …………………..
Components
Wires are usually covered in ……………
Plastic
What kind of circuit do Christmas tree lights use
Series
If one bulb was brokers why can’t the rest of the circuit
In a series circuit if one bulb breaks then the circuit is broken and all the lights go out
