Homework Statement
A 240 W television operates for 4.0 h a day in a typical Canadian home.
Calculate the resistance of the television.
Homework Equations
1) I = Q/∆ t 2) E = QxV 3) P = (Q x V)/ ∆t 4) P = I^2 x R
5) P = V^2/R 6) P = I x V 7) V = W/Q 8) V = E/Q
9) Q = I x ∆t 10) R = V/I
The Attempt at a Solution
Given:
P = 240 W
∆t = 4 h = 14 400 s
R = ?
E = P x ∆t
= 240 W x 14 400 s
= 3 456 000 J
I have done many practice problems but none such as this. I do not know where to go from here. There are many equations and I understand the most logical step next would be to either find the current or voltage and then using that value and Power to find the resistance. Or I can also find the value of Q and then using that and Power find either the current or voltage but not many values are given to do that.
Please help, I have been at this question for quite a while now, going around in circles.
