Electrical outlet wiring can be done in two ways: Ring main wiring In ring main wiring method a loop of each wire (Live, Neutral, and Phase) is made starting from the first outlet to last outlet and then again back to the original point. The ring main provides a two-way flow of power from one … Read more
An electrical outlet is a socket which connects electrical equipment to the electric supply. Many times you need to move the location of the electrical outlet from one point to another. Here is a simple video for moving an electrical outlet from one place to another. Must to do: Always call a registered technician and … Read more
Very often you came across transmission lines loaded with birds. Ever wondered that: Why birds are not electrocuted on power lines In this post, you’ll learn the answer. Electric current is defined as the rate of flow of electric charge from one point to another. The flow of electric current requires a potential difference between … Read more
A cable lug is a device used for connecting electrical cables to electrical appliances, surfaces, and other equipment. One commonplace for employing cable lugs in the electric industry is the power distribution boards. Cables are terminated into breakers, earth and neutral strips via cable lugs. Given below are the 6 most popular types of cable … Read more
Two-way wiring switch is used to control a lamp from two different locations. The figure below displays the connections for this type of wiring: Work Flow At instant suppose the light is turned on. If any position of the switches is changed then the LED (Lamp, bulb) will turn off. Again if switching position is … Read more
Electric Power is defined as the product of voltage and current. This post illustrates the SI unit of electrical power. SI unit of electric power is: volt (V) amps (A) watt (W) joule (J) Correct answer: 3. watt Explanation: From Basic Electrical and Electronics Engineering topics we know about voltage and current: Voltage: Unit is … Read more
Wiring single-phase split AC is a very easy task provided that proper tools and skilled hands at service. The diagram below is a general reference purpose diagram which illustrates generally the method of how Single-phase split AC units are installed. Depending on your model of AC the wiring can be different. For installation purposes always … Read more
PWM or pulse width modulation is a method used for reducing average power provided by a source by effectively dividing it into discrete parts. While a potentiometer is essentially a variable resistor having three terminals. This video illustrates the difference between both and when you should use a potentiometer and when you should employ PWM.
Statement: Three resistors of 15 ohms are connected in parallel. The equivalent resistance is: 12.5 ohms 10 ohms 5 ohms 3 ohms Answer: 5 ohms Discussion: Brief solution: The basic formula for parallel resistors is: In case of three resistors: 1/R(eq) = 1/R(1) + 1/R(2) + 1/R(3) Solving this we obtain R(eq) = 5 ohms … Read more
Why capacitor blocks DC while allows AC is one of the most popular question in Electrical and Electronics Engineering. But does capacitor actually blocks DC? This post provides to question Consider a parallel plate capacitor. Under normal conditions, the plates of capacitors contain a huge number of free electrons. Let’s consider a DC source that … Read more
