Series And Parallel Circuits Flashcards
What is current like in a series circuit?
The same everywhere
What is potential difference like in a series circuit?
It gets shared between the components. The bigger the resistance the bigger the share of potential difference
What is resistance like in a series circuit?
The resistance of the components adds up
What is current like in a parallel circuit?
It splits between the branches and adds back up in the main circuit
What is potential difference like in a parallel circuit?
The same as the supply
What is resistance like in a parallel circuit?
More comprenants= lower resistance.
this is because there are more roots for the current to take.
What is the formula for resistance?
Resistance= potential difference/ current
What is the formula for power?
Power= energy/ time
What is the formula for potential difference?
PD = energy/ charge
What is the formula for charge?
Charge= current ~ time
What does thermistor do?
Changes resistance with temperature
Why do comprenants with a greater resistance always have a higher share of voltage?
More force is required
