Homework Statement
A pot containing 15 kg of water at 30 C is heated until all the water is at 90 C, by placing a resistor (having resistance R=930Ω) in the water and running a current through it. What current must be placed through the resistor if the 15 kg of water is raised from 30 C to 90 C in 6 minutes? The specific heat of water is c=4186 j/kgxC), which is the energy needed to heat one kg of water 1 C.
Answer is in Amperes
Homework Equations
Q=MCdeltat I=delta q/delta t
The Attempt at a Solution
I plugged the information into the equations, but don't know how to include R=930Ω into the equations.
