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?
It decreases when you add resistors in parallel, its always less than the smallest resistor 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
