The power dissipated in a resistor is given by P = V2/R, which means power decreases if resistance increases. Yet this power is also given by P = I2R, which means power increases if resistance increases. Explain why there is no contradiction here.
When the switch S is open, the voltmeter V of the battery reads 3.05 V. When the switch is closed, the voltmeter reading drops to 2.88 V, and the ammeter A reads 1.57 A.

The recovery time of a hot water heater is the time required to heat all the water in the unit to the desired temperature. Suppose that a 20-gallon (1.00 gal = 3.79 x 10-3 m3) unit starts with water at 14 °C and delivers hot water at 55 °C. The unit is electric and uses a resistance heater (120 V AC, 3.4 Ω) to heat the water. If water has a specific heat capacity of 4186 J/(kg°C) and a density of 1000 kg/m3, and assuming that no heat is lost to the environment, what is the recovery time of this hot water heater?
