Electricity Flashcards
What do you measure the voltage in a circuit with?
A volt meter
What is current
The rate of flow of change through a circuit
What is voltage
Voltage is the potential difference across the circuit
What is electricity
Electricity is the flow of charge
What is a conductor
A conductor allows electricity to flow through it this is because it has lots of free electrons
What is a non conductor
A non conductor has a very high resistance it does not have as many free electrons making it hard for electricity to flow
What happens to light bulbs in a series circuit
They have to share the current
What happens to light bulbs in a parallel circuit
In a parallel circuit both light bulbs have full charge
What is the symbol for a resister
A square with lines coming out of it
What is the symbol for the ammeter
A circle with a A in it and two lines coming out
Voltage in a parallel circuit
In a parallel circuit the voltage is equal for each branch
Voltage in a parallel circuit
In a parallel circuit the voltage is equal across each branch
What is the symbol for a motor?
A circle with an m in it
What does current do in a parallel circuit
Split
What does current do in a series circuit
Same
