The voltage V is equal to 0.2 amps times 25 ohms, which is equal to 5 volts: V= 0.2A × 25Ω = 5V Ohms to volts calculation with watts The powerPis equal to the voltageVtimes the currentI: P=V×I The currentIis equal to the voltageVdivided by the resistanceR(ohm's law): ...
Once you get into the basics of how electricity functions, it won’t be long until you need to understand volts and watts. If you want to learn more about electricity besides just how to plug into a wall socket, understanding what volts and watts measure and how they’re interconnected is...
Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current. Using the example in Step 1, with a voltage of 50 volts and a current of 2 amps, the resistance ...
To find the amperage of a current based on the number of millivolts, you will need to know the number of watts produced by the current. Once you know the number of millivolts and watts, you can use the basic power conversion formula "Watts = Volts x Amps" to find the number of am...
What are amps, watts, volts and ohms? Is it possible to generate electricity directly from heat? Could I power my computer or my TV with a bicycle generator?

3.3 volts 5 volts 12 volts The 3.3 and 5 volts are typically used by digital circuits, while the 12 volt is used to run motors in disk drives and fans. The main specification of a power supply is in watts. A watt is the product of the voltage in volts and the current in amperes ...
You can find capacitors as big as soda cans that hold enough charge to light a flashlight for a minute or more. Even nature shows the capacitor at work in the form of lightning. One plate is the cloud, the other plate is the ground and the lightning is the charge releasing between ...
The LED draws about 45 milliamps with the battery producing about 1.23 volts (0.055 watts). It produces about half of the light that a candle would. The Nicad battery, when fully charged, can operate the LED for about 15 hours. Half of a candle's light is not very much, and if you...
