No, you have everything you need.
Suppose the resistor draws a current I, what is the power it dissipates?

 

[jmatthews1991]

P=vi

 

[jmatthews1991]

still very confuesed

 

[willem2]

P=vi

now give a formula for the power with only I and R in it (which are known).

hint: ohm's law

 

[jmatthews1991]

P=(IR)I ! ! ! ! Thank you so much !
