Calculate power/voltage/current??? - how to calculate the voltage of lights
How do I calculate the power / voltage / current by the following equation? both problems and please explain. thx.
I = V / R
How timely it is not necessary W lamp in a radius of 110 V?
What is the resistance of a lamp, to require a 110-volt power outlet a current of 0.2 A?

Firstly, you did not write that (to WW) from the bulb. And secondly, you need a different equation for the first problem.
Anyway ... the first question, the equation P = IV, the power (in watts) equal to current (I) voltage (V). To solve, take the power of the light bulb (not included above) and divide by 110 volts.
For the second problem, according to the formula I = V / R 0,2 amp plug in the variables I and put 110 volts in the variable V. To solve, divide 110 by 0.2 to a response from 550 of the resistance. The units of resistance is ohms.
