Electricity Flashcards
Conclusion about the current on a series circuit
The current is the Same at all points in a series circuit
How can you tell which is the positive and negative side in a cell symbol
Longer line is positive
shorter line is negative
What resistors do
Reduce the size of the current
What does a volt meter measure
Voltage
What does a ammeter measure
Current
Conclusion on a volt meter in a series circuit
Splits between outputs
Where does the ammeter go on a circuit
Anyhwere
Where does a voltmeter go on a circuit
Parallel to an output
Conclusion about current in a parallel circuit
Splits in a parallel circuit
Conclusion on the voltage in a parallel circuit
Voltage stays the same
What happens if a bulb blows in a circuit
Series components all go out
Parallel components still remain working
How to work out the resistance / ohms
Voltage (voltmeter) divided by the current (ammeter)
In a series circuit if there is 2 or more bulbs what happens
The voltage splits between them
In a parallel circuit and there is more than one bulb what voltage does each one get
The same as the voltage input
