A small-scale micro-hydroelectric generator has a power rating which varies from 1.0 kW1.0\text{ kW}1.0 kW to 3.5 kW3.5\text{ kW}3.5 kW.
The generator has an electrical resistance of 14 Ω14\text{ }\Omega14 Ω. It generates a current of 13 A13\text{ A}13 A when the water flow is high. Calculate the power output in kWkWkW of the generator on this day. Round your answer to one decimal place.
Suggest why the manufacturer gives a range for the power rating of the micro-hydroelectric generator.
Using just this generator may be an unreliable source of power for a house. State a reason why.
