Hello friends and welcome to my article in the SLC21/WK3 in this great dynamics, I would be putting in efforts to come up with creative and detailed article.


"Write two differences between current and voltage"

CurrentVoltage
Current is measured in amperes (A) special conductor which electrical changed surge fromVoltage is measured in volts (V) which shows potential difference which caused current flow.
It is represented by (I) symbol showing flow of electrons in the circuitIt represents force that positive electric charge surges through circuit.

"What two differences between an AC electricity and a DC electricity"

AC electricityDC electricity
AC electricity are used to generate power, commonly industrial workspace with heavy duty machines and sophisticated equipmentThis flows in domestic homes with household appliances generated from power stations.
This flows in an alternate direction with a complex speed needing frequency regulators to control them and basically flows in alternate mediumsThis flows in a unilateral direction that is one direction. For powering our household smartphones and a host of others.

"Write the difference between an AC motor and DC motor"

AC MotorsDC Motors
AC motor generates more power, commonly used in industrial parastatals making use of alternating current which changes with time.DC Motors are basically used in automobile and lots of heavy duty industries, running a direct current sequence thus current flows in one direction.
AC Motors has very complex and sophisticated speed control often requiring an operative to monitor and adjust then to the suiting of the momentThe velocity in speed is easy to be controlled with more accurate methods, as it is achieved by adjustment in voltage to the motor.

"Write two main differences between DOL, Star-Delta and forward reverse starter"


DOL


This is direct on line which connects motor directly to full time voltage at start up which causes motor directly to full line voltage at start-up with current significantly higher than full-load current. Bringing about 5X more.

It's quite cheaper and easily affordable. It is for motors that handle starting current. Relatively small motors where starting current Voltage could cause damage.


Star-Delta

This reduces starting current, connected in a star configurator shape to reduce current flow to a relative extent. It switches to delta configuration for full voltage operation.

Importantly, used in heavy duty industries where starting current needs to be reduced to reduce loss.


"Forward Reverse Starter"

It allows motie to run in multi lateral direction after changing phase sequence. It is used to control direction of rotation of a starter motor. It has little or no effect on starting current.

It is commonly used in escalator, elevators system and automobile company where need arises to reduce starting current but only controls direction of motor.


"Write the names and pictures of electrical switch gear uses in the home"

Fuse: This is main purpose is to control the electricity into home once it is removed it shuts the power out of the region

Distribution Board: It accepts current from the electric pole, steps down and lets the specific amount of current to be incorporated into the home, suitable for consumption.
