series circuits Flashcards
in series circuits how are different components connected together
they are connected in a line between +ve and -ve of the power supply
what happens if you remove or disconnect one component in the series circuit
the circuit is broken and they all stop
what is the total pd shared between in series circuits
the various components, so the potential differences around the series circuit always add up to the equal source of pd
what is the pd equal to (equation)
V = V1 + V2 + …
what is the current that flows through the series circuit
the same current flows between all components
what is the size of the current determined by
the total pd of the cells and the total resistance
how do you work out the size of a current
I = V/ R
how do you work out the total resistance in series circuits
the sum of all their resistances ( R =R1 + R2 )
what happens the bigger the component resistor
the bigger its share of total potential difference
