Electrical Converter ची गणना कशी करावी
Electrical Converter म्हणजे काय?
Electrical converters translate between voltage, current, resistance, power, and energy units (V, A, Ω, W, kW, kWh, etc.).
सूत्र
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
चरण-दर-चरण मार्गदर्शक
- 1Ohm's Law: V = I × R
- 2Power: P = V × I = I²R = V²/R
- 3Energy: E = P × t (watts × hours = watt-hours)
Worked Examples
इनपुट
120V, 10A circuit
परिणाम
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.
