Understanding the Two Key Formulas
⚡ Electrical Energy Formula
Electrical energy is calculated using:
- Voltage (V)
- Current (I)
- Time (t)
This helps determine how much electrical energy is consumed or produced in a system.
Example concept:
A bulb running for a certain time consumes energy based on voltage and current flow.
🔧 Mechanical Work Formula
Mechanical work is calculated using:
- Force (F)
- Distance (d)
This measures how much energy is used when an object is moved.
Example concept:
Pushing a box across a floor requires force over a distance, resulting in mechanical work.
Practical Example 1: Electrical Energy Calculation
Imagine you are studying an electrical appliance:
- Voltage = 220 V
- Current = 2 A
- Time = 5 seconds
The calculator computes:
- Energy = V × I × t
- Energy = 220 × 2 × 5
- Energy = 2200 Joules
Result:
The appliance consumes 2200 J of electrical energy in 5 seconds.
This is useful for understanding power consumption in household devices like fans, bulbs, or heaters.
Practical Example 2: Mechanical Work Calculation
Consider lifting a box:
- Force = 50 N
- Distance = 3 m
The calculator computes:
- Work = F × d
- Work = 50 × 3
- Work = 150 Joules
Result:
The total mechanical work done is 150 J.
This is useful in physics labs, engineering tasks, and real-life movement analysis.
