The following method assumes that you know how many amps you need for the gadget under power. If you know the watts go to Step A below. Step 1. Back of the envelope If the current drawn is x amps, the time is T hours then the capacity C in amp-hours is C = xT For example, ...

For example, if you can precharge the cap to +2.5 volts then the current peak reduces to around 1.6 amps, but interestingly if you can precharge the cap to the nominal USB voltage 5.0 volts, then the current peak is zero (0 amps). That would mean you could connect the circuit and ...
The heaviest alligator ever weighed was killed by Mike Cottingham in Arkansas in 2012. Cottingham's gator fight was much shorter at just 20 minutes, but his catch was so big he needed four friends to get it out of the water, and inside its stomach they found a five-foot-long alligator....
After passing a current of 0.375 Amps for 1.2 hours through the cell below, calculate the mass of copper deposited. Pt, H_2(1 bar)| H^+ (1m)||Cu^+2 (1 m)|Cu(s) What are the SI units of electrostatic potential and of chemical potential?
Calculate the total current of your load: Using the formula: Current = Power (in watts) / Voltage, you can determine how much current your solar system must generate to run the connected electrical load. Assuming the power to be 1000 watts and voltage as 24 volts, current = 41.66 amps. ...
Things Needed Pen or pencil Notepad TL;DR (Too Long; Didn't Read) The prefix "milli" means thousandths and "kilo" means thousands. For example, 50 milliamps equals .05 amps, 10 KW means 10,000 watts and 5 KVA means 5,000 volt/amps. Volt/amps and watts actually mean the same thing...
Horsepower is a measure of power, and voltage measures the amount of energy carried in a circuit. Current, measured in amps, represents how fast the energy moves through a circuit. For example, you might use horsepower and voltage to find the current in a motor. In order to calculate the...
Using spreadsheets to calculate errors can save valuable time, particularly when changes are needed. Figure 6 shows a spreadsheet used to calculate total error based on worst-case errors pulled from the data sheet. The root sum of squares (RSS) analysis, where total error is ...
Electronics is fairly new to me and there are things I do not understand, but I want to learn. Right now I am facing some difficulties in fully understanding how I should proceed when calculating the values. http://www.ti.com/lit/ds/symlink/tl494.pdf...
