They do need sunlight to work if you want to power your house so you can plug in the light to charge the batteries, the sun first needs to power up the batteries so you can continue the cycle. But they can also work with a regular lighting.
You need this formula:
Watts = Amps * Volts
100 watts = x amps * 120 volts
100 watts / 120 volts = ~.83 amps
Or you can manage the amps by testing it with a test equipment.
V = W/A
voltage is like water pressure
amperage is like water flow
ohms is resistance
current equals voltage divided by resistance.
Test the proper volts with a test equipment now.
Connect a power source to the circuit (+ve terminal to one side of the resistor and -ve terminal to the other) then connect a voltmeter in parallel with the resistor. The reading on the voltmeter will provide a measure of the potential difference across the circuit (ie: The voltage drop
across it). Voltmeter are now … Read more
Basically, a
pulley changes the direction of an applied force. Thus, for instance,
you can pull on the cable of the pulley, and it will pull a weight.
Perspex widely used for watch glasses, advertising signs, domestic baths, motorboat windscreens, aircraft canopies, and protective shields. Helpful test equipment for you is now available online.
The best way to identify transistors is by the type number marked or on the circuit diagram.
Electromagnetic crane has a huge electric magnet instead of a hook. This magnet is operated by an electrical current. When electric is switched on the magnet becomes magnetized,allowing metal objects to be picked up just like an ordinary magnet. When electric is turned off the metal object will fall away, as it … Read more
