series circuits

there is a bigger potential difference when more cells are connected in series

in series circuits the total pd is shared between various components

V(total)=V1+V2+...etc

in series circuits the same current flows through all parts of circuits

I(total)=I1=I2=...etc

V=IR

size of current is determined by the total pd of the cells and the total resistance of the circuit using this equation

in series circuits the total resistance is just the sum of all the resistances:

R(total)=R1+R2+...etc

adding a resistor in series increases the total resistance because the resistor has to take a share of pd.

this decreases the pd through each…
