How to Use an Electric Power Calculator?

MathCalc designed this free Electric Power Calculator to navigate and calculate electric power without any deep knowledge of electric current or physics behind it. By following the simple steps, you can calculate cost, control, or consumption.

Step 1: Select What You Want To Calculate

You can find three options, power, consumption, and cost, from the drop-down menu in the Electric Power Calculator. Select the type of calculation.

Step 2: Enter The Input Values

You need to enter the relevant data in the relevant sections. All the required data can be found in the device manual, the electricity bill, or from the given data of your problem. Just type the values with the correct units.
V = voltage
W = Wattage (how much power a device uses)
Hour = how many hours a day you use that device
Cost = electricity rate (you can find it on your bill)

Step 3: Click The Calculate Button

After entering all the relevant data, press the Calculate button present at the bottom right, and you will instantly get your results.

How Does It Work? - Science Behind The Scene

Our free Electric Power Calculator uses simple math rules and formulas to calculate the electric power, energy and cost. Here’s how this calculator works:

To calculate power

Given:

• Voltage (V) = 220 V
• Current (I) = 5 A

Steps:

• Step 1: Electric Power Calculation
• Step 2: Power formula: P = V × I
• Step 3: Given: V = 220 V, I = 5 A
• Step 4: P = 220 × 5 = 1100 W

Result:

Power = 1100 W

To calculate Energy Consumption

Given:

• Voltage (V) = 220 V
• Current (I) = 5 A
• Power (P) = 1100 W
• Time (t) = 3 hours

Steps:

• Step 1: Energy Consumption Calculation
• Step 2: Energy formula: E= P × t
• Step 3: Given: P= 1100 W, t = 3 hours
• Step 4: E= 1100 × 3 = 3300 Wh
• Step 5: E= 3300/1000 = 3.3 kWh

Result:

• Energy wh: 3300 Wh
• Energy kWh: 3.3 kWh

To calculate Electricity Cost Calculation

Given:

• Voltage (V) = 220 volts
• Current (I) = 5 amps
• Energy Consumption = 3.3 kWh
• Time = 3 hours
• Cost per kWh = Rs. 30

Steps:

• Step 1: Electricity Cost Calculation
• Step 2: Energy: E = P × t = 1100 W × 3 h = 3300 Wh = 3.3 kWh
• Step 3: Cost: C = E × rate = 3.3 kWh × $30/kWh = $99

Result:

• Energy kWh: 3.3 kWh
• Cost: $99.00
• Pretty cool, right? It’s that easy!
