The steps required for testing of a diode rectifier are as follows. Take a good quality digital multimeter Set the range in the diode position On the display you should get a 3 or an infinite voltage reading depending upon the multimeter used Connect the red probe to the cathode and the black probe to … Continue reading Diode Testing
This article explains the characteristics and use of diode rectifier circuits, as well as detailed information regarding the process of rectification. The article also deals with testing procedures in simple steps that can be very handy for new electronic enthusiasts.Introduction: A diode rectifier is a semiconductor device and comes under 'active' electronic components. Its basic … Continue reading Understanding Rectifier Diodes
In an electronic circuit, the basic function of a resistor is to limit the current to a safe value so that the associated sophisticated parts can function properly.

Former South African President Nelson Mandela as his family lays his body to rest in his hometown of Qunu, South Africa, on Sunday December 15. Mandela's body traveled from Pretoria by air to Mthatha in Eastern Cape province, and then by road to Qunu, where was buried Sunday. Mandela died December 5 at his home … Continue reading Mandela laid to rest in Qunu(HIS CHILHOOD VILLAGE), ending a journey that transformed South Africa
New operators in the nation’s power sector have asked for increase in electricity tariff in the midst of worsening power situation in the country. The operators have already jerked up service charge from N750 to N1,500 monthly. This came as the Federal Government and organized labour are meeting today to review labour issues in the … Continue reading Electricity: New Owners Demand Increase in Tariff
The landing makes China one of only three nations -- after the United States and the former Soviet Union -- to "soft-land" on the moon's surface, and the first to do so in more than three decades. Chang'e-3, an unmanned spacecraft, will release Jade Rabbit (called Yutu in Chinese) -- a six-wheeled lunar rover equipped … Continue reading China’s first lunar rover landed on the moon Saturday, less than two weeks after it blasted off from Earth.
A resistor is nothing magic. Take a long wire and measure the resistance, and you will realize that resistance is just a normal property of wires (except for superconductors). Some resistors are made up of just that. A long wire. But you can also find resistors made of other types of materials. Like this carbon … Continue reading What is a resistor
It is the magnitude of current and the time duration that produces effect. That means a low value current for a long duration can also be fatal. The safe current/time limit for a victim to survive at 500mA is 0.2 seconds and at 50 mA is 2 seconds. The voltage of the electric supply is … Continue reading Facts about Electric Shock
What are the physical differences between shocks by AC and DC current? Both are dangerous and can be lethal in high amounts. Learn more here. Difference between AC and DC CurrentAn AC current is alternating in nature and follows a sine curve. It is continuously changing direction and passing through zero to a maximum positive … Continue reading What’s the Difference Between AC and DC Electric Shocks?
