In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
The power of the torch bulb is 1.25 watts calculated as P = V * I, where V is 2.5V and I is 500mA converted to 0.5A.
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
100 watt
There are 1,000 watts in a kilowatt (kW).
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
1,175 watts. Which isn't very feasible As it infers a voltage of 2350 Volts across the resistor. Pls recheck you numbers and resubmit
Assuming your using a USB port to power your device, the answer is 2.5 Watts. A maximum of 500mA at 5V can be drawn from a Usb port. Power = Current * Voltage, which is 2.5 Watts by 0.5 Amps giving you a power output of 2.5 Watts http://en.wikipedia.org/wiki/USB#Power http://en.wikipedia.org/wiki/Power_(physics)#Average_electrical_power_for_AC
