Electrical Converter ની ગણતરી કેવી રીતે કરવી
Electrical Converter શું છે?
Electrical converters translate between voltage, current, resistance, power, and energy units (V, A, Ω, W, kW, kWh, etc.).
સૂત્ર
Ohm\'s Law: V = I × R
- V
- I²R = V²/R — I²R = V²/R
- I
- I²R = V²/R — I²R = V²/R
- R
- R value — Variable used in the calculation
પગલું દ્વારા પગલું માર્ગદર્શિકા
- 1Ohm's Law: V = I × R
- 2Power: P = V × I = I²R = V²/R
- 3Energy: E = P × t (watts × hours = watt-hours)
Worked Examples
ઇનપુટ
120V, 10A circuit
પરિણામ
Resistance 12Ω, power 1200W, daily energy (24hr) 28.8 kWh
Typical household
Common Mistakes to Avoid
- ✕Adding watts from different circuits (totals correctly)
- ✕Confusing kW with kWh (power vs. energy)
Frequently Asked Questions
Why distinguish watts from watt-hours?
Watts = instantaneous power; watt-hours = total energy used. Bills charge for energy, not power.
How do you reduce electrical cost?
Reduce watts (efficient appliances) or reduce hours (use less). Biggest impacts: heating, cooling, water heating.
