The equation I2R seems to suggest that the rate of heating in a resistor is reduced if resistance decreases, whereas equation P = V2/R suggests just the opposite. How do you reconcile this problem?

उत्तर
There is no contradiction in the relation. It V is constant, on decreasing resistance, the current increases and so as P = I2R the same result we gets from equation P = V2/R.
