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 मार्गदर्शिका

  1. 1Ohm's Law: V = I × R
  2. 2Power: P = V × I = I²R = V²/R
  3. 3Energy: E = P × t (watts × hours = watt-hours)

हल किए गए उदाहरण

इनपुट
120V, 10A circuit
परिणाम
Resistance 12Ω, power 1200W, daily energy (24hr) 28.8 kWh
Typical household

सामान्य गलतियां जिनसे बचना है

  • Adding watts from different circuits (totals correctly)
  • Confusing kW with kWh (power vs. energy)

अक्सर पूछे जाने वाले प्रश्न

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.
