Task 1

Task 2

• Alternating Voltage: From research, alternating voltage distributes electric power in a circuit. It is called alternating because the voltage changes magnitude and direction with respect to time. The variation in voltage may be regular or irregular periodically.

• Direct Voltage: Direct voltage transmits constant current in one direction in a circuit.

• Resistance: Resistance is a measure to determine how readily current will flow in a circuit. It is measure in ohms

• Potentiometer: A potentiometer is a measuring instrument use to determine the potential difference of a voltage by comparing it's know voltage with the unknown voltage.

• Rectifier diode: A diode acts as a channel allowing current to pass through it or block it. A rectifier diode is an electronic device that changes alternating current into a direct current by using one or more P-N junction diodes.

• Diode bridge: diode bridge comprises of 4-6 diodes connected as one for rectifying alternating current to direct current.

• Capacitor: A capacitor is a 2 way terminal electric device use to store electric energy/charges.

• Transistor: This is a semiconductor for amplifying and rectifying electrical signals and power/ current and voltage

• Transformer: Transformer is use to step down or step up voltage. A transfer is a device that transfers electric energy from one alternating current circuit to one or more circuit.

• Fuse: A fuse is a device that breaks down or interrupt the flow of electric current passing through it when it's above normal. It is an electronic safety device.

• Lithium battery: This is a kind of rechargeable battery that used lithium-ion or Li-ion
