First, set the rotary switch to voltage. In the case of DC voltage, the unit of voltage "V" and the mark indicating DC are displayed as shown in the figure. For AC voltage, set to the parameter which shows unit "V" and the mark indicating AC. 2. Insert the test leads Insert the...
Unlike water, which is used as it comes from the tap, electricity is meant to do work: It is converted from energy to power, measured in watts. Since household electrical consumption is relatively high, the unit of measure most often used is the kilowatt, which is equal to 1,000 watts....

Electric engineers in the U.S. are typically paid six-figure salaries, according to federal statistics. Electrical engineers work in a wide array of industries and are responsible for a dizzying amount of innovation. Many of the most common, useful devices that make modern life...
We've seenothers in the industryput the figure at closer to 3 kW, but if you're unsure, you can run through all the math for your situation. How many solar panels will I need to power my whole home? This basically comes down to figuring out your home's total energy needs and then...
Figure 1: An electrical engineer reviewing a start/stop switch for a variable frequency drive. Courtesy: Hedgehog Technologies This marks a significant departure from older VFD models that operated on fixed or less flexible parameters. Unlike older VFDs, which often had efficiencies below 85%, certa...
So how much money can you make selling electricity back to the grid? Since rates vary with the market value of electricity, there's no set dollar figure that you can expect to take home. However, some home producersmake from $0.04 to $0.08per kWh sold back to the grid. ...
Figure 2. 3- and 4-wire fans. Fan Control No control: The simplest method of fan control is not to use any at all; just run a fan of appropriate capacity at full speed 100% of the time. The main advantages of this are guaranteed fail-safe cooling and a very simple external circuit...
