Frequently Asked Questions
How do I calculate my electricity consumption?
To calculate electricity consumption, multiply the power rating (in watts) of your appliance by the number of hours it's used, then divide by 1000 to get kilowatt-hours (kWh). For example, a 100W bulb used for 10 hours consumes 1 kWh of electricity.
What is the difference between series and parallel circuits?
In a series circuit, components are connected end-to-end, creating a single path for current flow. The total resistance is the sum of all resistances. In a parallel circuit, components are connected across the same two points, creating multiple paths for current. The total resistance is less than any individual resistance.
How do I convert between different power units?
To convert between power units: 1 kilowatt (kW) = 1000 watts (W), 1 megawatt (MW) = 1000 kilowatts, 1 horsepower (hp) = 745.7 watts, and 1 BTU/hour = 0.293 watts. Multiply or divide by these conversion factors to change between units.
