Whether you’re invested in greener energy solutions or curbing rising energy costs, monitoring and managing home energy electricity is a priority for many UK residents. Not only does understanding your consumption contribute to a more sustainable lifestyle, but it can also lead to significant saving...
Transistors had many advantages: high reliability, low power consumption and small size compared to tubes or relays. These transistors were discrete devices, meaning that each transistor was a separate device. Each one came in a little metal can about the size of a pea with three wires attached...
Recently I built aSMD reflow ovenusing a toaster oven and acontroller kit. This has made it really easy to solder up SMD PCBs (surface mount device printed circuit boards). You simply put blobs of solder paste on the pads, drop the SMD parts into place, put in the reflow oven and bake...
Many appliances have a very high inductive start-up load. The start-up load is the power it takes to get an electric motor moving. All electric motors draw the most power and produce the most torque while starting up. These loads are often 2-3 times higher than the operating load. Natur...
A refrigerator, for example, might draw up to 15 amps initially but will quickly settle down to around 4 amps. Suppose the refrigerator is plugged into a 20-amp branch circuit and a 1,000-watt electric toaster (which draws a little more than 8 amps) is also plugged into that circuit. ...
It should never be used, however, to plug in a space heater or other high-power devices, or a power bar loaded with too many devices such as a TV screen, AV units, a cable box, etc. B) The 3-prong 20 Amps 125 volts receptacle basically has the same appearance as the 3-prongs ...
there’s a good chance that you’ll have to live with all of its imperfections and frustrations for many years to come, every time the breaker trips while starting the microwave oven or the toaster while something else is on, or when you have to move closer to an outlet with your bowl...

Solenoid continuity: Many appliances that use water, such as a dishwasher or a refrigerator with an ice maker, will have a solenoid valve, (a valve opened and closed by a small electro magnet). A small break in the solenoid's electrical coil will cause the valve to stop working. You can...
