A student builds a circuit that has a source of electrical energy, connecting wires, a switch, and a load. However, the circuit does not work. Suggest three possible reasons why the circuit does not work.

Explanation:

1. The load has been burned out in a previous experiment. It is now an open circuit.

2. The switch may not be closed.

3. The energy source is now discharged.

4. The wires are touching creating a short circuit.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
