## Energy calculator

$$ E = P t $$

\(E \, \) is energy
in joules (J)

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

\(t \, \) is time
in seconds (s)

\( E \)

= \( P t \)

= \( \mathrm{ W } \) \( \times \) \( \mathrm{ s } \)

= \( \mathrm{ J } \)

= \( \mathrm{ J } \)

\( P \)

= \( \displaystyle{\frac{ E }{ t }} \)

= \( \mathrm{ J } \) \( \div \) \( \mathrm{ s } \)

= \( \mathrm{ W } \)

= \( \mathrm{ W } \)

\( t \)

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

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

= \( \mathrm{ s } \)

= \( \mathrm{ s } \)
