    Split ring commutator - the purpose is for current to be flowing into the coil in the same direction so the direction of movement of the coil is always the same. Slip rings - they ensure that the induced current in a.c. generator is transmitted through to the circuit (in other words, it connects...

    Remember these tips: - Best fit lines mean that a strong correlation with the line passing through the middle (i.e. equal number of points above and below the line). - The line WILL not NECESSARILY pass through the origin (Don't try to pass it through the origin every time). - Use a sharp pencil...
