How many watts are in a 500 ma 12v dc?
In ideal conditions, about 6W Amps x volts = watts 500ma = 1/2 amp (1000ma to 1a) 0.5 X 12V = 6W
What is power of torch bulb rated at 2.5v and 500m a?
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?

How many watts in 0.5 kW?
100 watt
How many watts in a kw?
There are 1,000 watts in a kilowatt (kW).
What is the power when there are 500mA of current through a 4.7k Ω resistor?
p=i square x r = 500ma * 500ma = .25 * 4.7k = 1175 watts
How many watts per hour will a unit that is rated at DC 12V 500mA consume?
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second

How many watts does the iPhone charger use?
The batter uses 5 Volts for charging and it takes 1 hour to fully charge your iphone which is 7 Watts.
What does 500mA equal to?
500mA = 500 miliamper 1000mA = 1 amp so 500mA = .5 amps
What is power of torch bulb rated at 2.5v and 500m a?
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.
What is the difference between output 30V 500mA with output 12V DC 700mA?
30 Volts 500ma means: 30volts, AC or DC not specified, at a rate of 500ma = roughly 15 watts electrical energy supplied. With out the AC or DC specified no gues on what it could be used for can be made. 12 V DC 700ma means: 12 Volt Direct Current with a supply rate of 700ma roughly 8.4 watts. This type of power supply common for things like cell phone chargers, Small battery charges for things like AA or AAA Nicad or Lithium Batteries.

How much power is produced by 500mA of current through 4.7kΩ resistor?
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
How much power can be supplied to any appliance by a laptop?
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
