1) WHICH IS THE MOST CONDUCTIVE AMONG THE FOLLOWING

2) WHICH IS MORE USED FOR ITS ABUNDANCE AND CHEAPER PRICE

• "VOLTAGE STORE"

• - An electrical device that supplies electric power to an electrical load.

• - The primary function is to convert electric current from a source to the correct voltage, current, and frequency to power the load.

• Cells, Batteries, voltage outlets, and transformers are the most common power supply devices.

is a connection to the earth that actually is important in every circuit

• used to prevent overload from shutting down all devices by exploding.

•  raises or lowers the voltage as needed.

• (OUTPUT DEVICES)

• An electrical device that converts energy from one form to another.

• Examples:

  • Electrical motor: electrical energy to mechanical energy

  • LED, fluorescent & incandescent lights: electrical energy to light energy

  • Speaker & buzzer: electrical energy to sound energy

a passive two-terminal component that stores energy in a magnetic field

- removes unwanted signals from other components

An electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another.

(SWITCHES)

• sually used for digital timers and alarms

(SWITCHES)

used for buzzers

(SWITCHES)

 A 2-way changeover switch directs the flow of current to one of two routes according to its position.

(SWITCHES)

• A dual on-off switch which is often used to switch mains electricity because it can.

• - A passive two-terminal electrical component that implements electrical resistance.

• - is an electrical component that impedes or slows down the flow of electrical current in an electronic circuit.

WHAT ARE THE 2 TYPES OF RESISTOR

can change the value of resistance; has a minimum and maximum value

Have a defined ohmic resistance and are not adjustable, and are the most used resistor electronic component.

Most used resistors electronic components ??

Are a blend of carbon particles, graphite, and ceramic dust mixed with a blender substance like clay treated with high temperature and pressure.

RESISTOR COLOR CODE:

1ST - ?
2ND - ?

3RD - ?

4TH - ?

• how accurate is the resistance 

• the color closest to the edge is the first value

• Formed by wounding a wire made up of resistive material around a core

• The metallic core acts as a non-conductive material while the resistive wire conducts, but with some resistance.

• Are rectangular in shape 

• They have a metallized area at either end of the main ceramic body, and in this way they can be set onto a printed circuit board that has pads onto which the two ends are set to provide the connection.

• Changes the flow of current in a controlled manner by offering a wide range of resistances

• Ex. Potentiometer

• Temporary battery

• A two-terminal electrical component

• Also one of the most fundamental passive components

Created out of two metal plates and an insulating material called a dielectric.

are insulative components

From chemical it will be turned into another energy

• Are devices that control the movement of electrons, and consequently, electricity.

• They work something like a water faucet — not only do they start and stop the flow of a current but they also control the amount of the current (amplifier)

• Ex. Traffic lights

TYPES OF TRANSISTORS

Invented by William Shockley and John Bardee. It’s a bidirectional device that uses both electrons and holes as charge carriers.

A TYPE OF BJT

One p-type semiconductor resides between two n-type semiconductors

A TYPE OF BJT

• An n-type semiconductor is sandwiched between two p-type semiconductors.

It consists of a channel of N- or P-type semiconductor material through which current can flow, with a different material controlling the conductivity of the channel.

- One end of the channel is known as the source, the other end of the channel is called the drain, and the control mechanism is called the gate.

- By applying a voltage to the gate, you control the flow of current from the source to the drain.

● Ammeter - _________

● Voltmeter - ________

● Ohmmeter - _________

● Galvanometer - _________

is an electrical device allowing current to move through it in one direction with far greater ease than in the other.

Movement of current/ electrons repetitively and moves forward and backward/ upward and downward
