क्या है Power Calculator?

▾

A power calculator computes electrical power (watts), and can find any unknown from P=VI, P=I²R, or P=V²/R. Also converts between watts, kilowatts, horsepower, and BTU/hr.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

सूत्र

▾

f(x)Power = base^exponent; bⁿ = b × b × b... (n times); b⁰ = 1; b⁻ⁿ = 1/bⁿ

कैसे Power Calculator

▾

1P = V × I (Power = Voltage × Current)
2P = I² × R (using current and resistance)
3P = V² / R (using voltage and resistance)
41 kW = 1,000 W; 1 HP = 745.7 W; 1 BTU/hr = 0.293 W

अक्सर पूछे जाने वाले प्रश्न

▾

What does 2^10 equal?

2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 1024.

How do negative exponents work?

2⁻³ = 1/2³ = 1/8 = 0.125. Negative exponent = reciprocal.

What's the difference between 2^3 and 3^2?

2³ = 8 (2 × 2 × 2). 3² = 9 (3 × 3). Order matters.
