You are given a spotlight which takes 2 amperes of current designed to work off a 6-volt battery. If the available source is a 12-V battery, what values of resistance would you need to connect in series with the spotlight before you could safely switch it on? Draw the circuit diagram and show the values of voltages and currents.
