A student investigates how the current through a filament light bulb varies with the potential difference across it.
(a) Draw a diagram of a circuit the student could use to obtain suitable measurements for a range of
potential difference from 0 V to 12 V.

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6
