## Power calculator

$$ P = V I $$

\(P \, \) is power
in watts (W)

\(V \, \) is voltage
in volts (V)

\(I \, \) is current
in amperes (A)

\( P \)

= \( V I \)

= \( \mathrm{ V } \) \( \times \) \( \mathrm{ A } \)

= \( \mathrm{ W } \)

= \( \mathrm{ W } \)

\( V \)

= \( \displaystyle{\frac{ P }{ I }} \)

= \( \mathrm{ W } \) \( \div \) \( \mathrm{ A } \)

= \( \mathrm{ V } \)

= \( \mathrm{ V } \)

\( I \)

= \( \displaystyle{\frac{ P }{ V }} \)

= \( \mathrm{ W } \) \( \div \) \( \mathrm{ V } \)

= \( \mathrm{ A } \)

= \( \mathrm{ A } \)
