To solve the problem, we need to express 1 kilowatt-hour (kWh) in terms of volts, amperes, and another quantity. Let's break it down step by step. ### Step 1: Understand the definition of 1 kWh 1 kilowatt-hour is defined as the amount of energy consumed when 1 kilowatt (kW) of power is used for 1 hour. ### Step 2: Convert kilowatts to watts 1 kilowatt (kW) is equal to 1000 watts (W). Therefore, we can express 1 kWh as: \[ ...
