If the resistance doubles while the voltage stays the same, what effect will that have on the power?

Question

anonymous · Answer

power is voltage*current
and voltage=resistance*current

anonymous · Answer

if you keep voltage the same, but double resistance, you must halve the current

anonymous · Answer

so you're power will be half of what it was before

cherio12: Please don't just give the solution to a question. Especially when it's probably homework. You are violating the code of conduct [1] - stop it. 1. http://openstudy.com/code-of-conduct

What the ... You just gave him/her the answer without even trying to guide him/her there. You are explicitly told to _not_ do this. Read the code of conduct please.

anonymous · Answer

It isnt my homework it's for a pretest. and it did not give me an equation.

anonymous · Answer

It isn't about using any specific formalism - he straight up gave you the answer. A thing he explicitly should not do. 
Not much of a problem if he keeps from doing so in the future. The thing that pisses me off is him trying to talk his way out of it instead of just admitting his mistake and maybe read the darn thing (Code of Conduct) for once..
