Design a Circuit

CircuitsThe bulb will only light if there is a battery

and a complete circuit.

Will the lamps light?

Designing Electrical Circuits

For safety reasons you have to make sue that if one headlight goes out the other stays on.

Build a circuit with two bulbs so that if one is unscrewed the other stays on.

and off separately.

Build a circuit with two bulbs where each bulb can be switched on or off without affecting the other

Reading Lights

A car needs a mechanism which makes sure lights cannot be left on by mistake. (If the ignition is off the car lights should go off too.)

Construct a circuit with two bulbs where each bulb can be switch on or off without affecting the other.

Include a master switch so that the bulbs only work when this master switch is on
