Activity 2. Electrical Components & Functions

Name	Picture	Function
Capacitor	*	Stores electric charge and is mainly used with resistors in timing circuits. Acts as a filter by passing AC and blocks DC.
Switch		Able to cut the flow of electricity
LDR (Light Dependent Resistor)		Change the brightness of alight in different weather conditions
Lamp Holder		To hold the lamp bulb in its place and connect it to the circuit easily
Multimeter cable		Connects the components of the circuit to a multimeter
Light Bulb		Turns electricity into visible illumination
LED		To test whether the circuit is working in which it will illuminate
Electrical wire		To connect to components of a circuit together
Magnetic Coil		To actuate relays (weak current closes contact for strong current circuit)
Resistor		To contain the flow of electric current in an electronic circuit.
Circuit Board		For routing power to a direct place based on activity.
Power Supply		Supply an electrical circuit with electrical power
U Magnet		To compensate for the very weak strength of bar magnet
Compass		Showing the direction of magnetic north and the bearings of it
Ampermeter		To measure electrical current in wires. To measure the change in current.
Galvanometer		To measure electric current
Battery		Used to operate lighting and accessory systems.
Multimeter		Used to measure different electrical related things (multi functional)
Variable Resistor		To provide variable resistances circuitry
Resistance Coil		To resist changes in electric current passing through it
