Electricity plays a crucial role in our everyday lives, powering homes, businesses, factories, and infrastructure. Whether you're an engineer, student, electrician, or homeowner, understanding how to calculate various electrical parameters like power, voltage, current, and energy consumption is essential. This Electricity Calculator is designed to make your calculations fast, easy, and accurate.
An electricity calculator is a digital tool that allows users to calculate various electrical values based on simple input parameters. These values typically include:
With the right formulas and input values, the calculator can solve for any of the variables in Ohm’s Law and power equations.
There are many reasons why someone may need to calculate electrical values. These include:
An electricity calculator saves time, reduces human error, and makes complex calculations accessible to users at all skill levels.
Voltage is the electrical potential difference between two points. It is measured in volts (V).
Current is the flow of electric charge through a conductor. It is measured in amperes (A).
Resistance is the opposition to the flow of current in a circuit. It is measured in ohms (Ω).
Power is the rate at which electrical energy is transferred by an electric circuit. It is measured in watts (W).
Ohm’s Law is the fundamental relationship between voltage, current, and resistance:
V = I × R
I = V / R
R = V / I
There are several equations for calculating power:
These formulas allow you to calculate power in different ways depending on what values you have.
Energy consumption is typically measured in kilowatt-hours (kWh). It can be calculated with:
Energy (kWh) = Power (kW) × Time (h)
To convert watts to kilowatts, divide by 1000.
A 1000 W appliance used for 3 hours consumes:
1000 W ÷ 1000 = 1 kW
1 kW × 3 h = 3 kWh
To estimate your electricity bill:
Cost = Energy (kWh) × Rate per kWh
If the rate is $0.15/kWh and usage is 200 kWh:
200 × 0.15 = $30
Calculate the daily, monthly, or annual energy consumption of devices like:
Use the calculator to size your solar system based on:
Determine energy consumption and cost of:
Estimate:
Students can use this calculator to explore:
Given:
Solution:
P = V × I = 230 × 5 = 1150 W
Device: 60 W light bulb
Usage: 5 hours/day
Daily Energy = (60 ÷ 1000) × 5 = 0.3 kWh
Monthly Energy = 0.3 × 30 = 9 kWh
For three-phase systems, use the formula:
P = √3 × V × I × PF
Battery energy in watt-hours (Wh) = Voltage × Capacity (Ah)
12V battery with 10Ah = 12 × 10 = 120Wh
If the load is 60W, runtime = 120 ÷ 60 = 2 hours
Modern electricity monitoring tools use smart meters and IoT platforms to:
