1. Take a battery, battery clip, and buzzer. Make the buzzer buzz.
2. Reverse the buzzer. Does it still work?
3. Notice the indicators for the positive terminal on the battery and on the buzzer. The flow of charge (current) is traditionally drawn from the positive terminal to the negative terminal. The positive terminal is traditionally red and the negative terminal is black.
Q.1 Sketch your circuit, including an indication of the positive terminals on the battery and the buzzer.
Q.2 Sketch your circuit, including an indication of the positive terminals.
Q.3 Connect your circuit with the switch to the circuit board. Make sure it still works. Make a sketch of it.
Q.4 A circuit diagram for the circuit without a switch is shown. Draw a circuit diagram for your circuit with the switch.
6. Replace your N.O. switch with a normally closed (N.C.) switch.
Q.5 What happens?
Q.6 Draw a circuit diagram for the resulting circuit.
