Technical Drawing (pre-test)

Its main function is to reduce voltage and to limit the flow of current in a circuit.

• Fixed Resistor

• Capacitor

• Resistor

• Diode

It can store electric charge even though the voltage source is already disconnected and it can discharge electrical voltages.

• Capacitor

• Diode

• Battery

• Resistor

This made of N-material and P-material (Positive and Negative devices) that are joined in a single package.

• Fixed Resistor

• Battery

• Diode

• Capacitor

It is a material which resists between the insulator and the conductor.

• Semiconductor

• Fixed Resistor

• Battery

• Zener Diode

It is a single value resistance, which remains the same under the normal condition.

• Rectifier Diode

• Zener Diode

• Switch

• Fixed Resistor

Both devices, have a sliding arm that brings into contact with the resistance element.

• Resistor Power Rating

• Light Emitting Diode

• Variable Resistor

• Rectifier Diode

Changes with their sizes, the bigger the resistor the greater wattages and the smaller the resistor the lesser wattage.
