the question reads...
" A 12V battery, of negligible internal resistance is connected to the fixed terminals of a variable potential divider, which has a maximum resistance of 50 ohms. a 12V light bulb is connected between the sliding contact and the negative terminal of the potential divider. sketh the circuit diagram and describe how the brightness of the light bulb changes when the sliding contact is moved from the negative to positive terminal of the potential divider.
any help would be greatly appreciated! :D
