Car headlight circuit - is this possible or do I need two separate circuit diagrams?
I have the following components:
12 Volt Battery, 1 x Double filament lamp, two switches (assume stay closed when switched).
Draw a circuit diagram using these components which would allow:
a) either filament can be switched on separately AND
b) both filaments switched on at the same time.

Such a circuit is possible. Put one filament and one switch in each of two parallel legs of a series-parallel circuit connected to the 12 V battery. This will allow current to go through either or nboth filaments

To switch them on or off at the same time, a third single-pole single-throw switch could be ued in the series part of the circuit.

The lamps are both 12 Volts, only two switches are available.
