Answer to Question #154568 in Molecular Physics | Thermodynamics for Thami

Question

What is the formula for power?

Answer 1

Power (watt, W) $= \frac{Energy \;transfromed \; (joule, \;J)}{Time \;(seconds, \;s)}$

$P = \frac{E}{t}$

Power can also be calculated using the formula

Power (watt, W) = (Potential difference (volt, V)) $\times$ Current (amp, A)

$P = V \times I$
