| In a series circuit can current ever be lost | No because it is impossible for eletrons to escape through a wire |
| In a series circuit what is the potential difference equal to | V=V1+V2 |
| What do you have to take into account when determining the voltage of a cell | the polarity i.e if it is facing againt another cell then no voltage wil flow. |
| Apart from the potential difference, emf what also adds up to give the total in a series cicuit | Resistance R=R1+R2 |
| In parallel what is the equation for current | We know what the resistance and voltage is as the voltage is constant all the way through in a parallel circuit. Using the resistance that is given we can work out that the current at that point = V/R(of the component). We do this for all components giving you the total current |
| Express 1/R=1/R1+1/R2 in another way (this is only used in a parallel circuit) | R=R1xR2 ----- R1+R2 |
