Energy calculator
$$ E = P t $$
\(E \, \) is energy
in joules (J)
\(P \, \) is power
in watts (W)
\(t \, \) is time
in seconds (s)
\( E \)
= \( P t \)
= \( \mathrm{ W } \) \( \times \) \( \mathrm{ s } \)
= \( \mathrm{ J } \)
= \( \mathrm{ J } \)
\( P \)
= \( \displaystyle{\frac{ E }{ t }} \)
= \( \mathrm{ J } \) \( \div \) \( \mathrm{ s } \)
= \( \mathrm{ W } \)
= \( \mathrm{ W } \)
\( t \)
= \( \displaystyle{\frac{ E }{ P }} \)
= \( \mathrm{ J } \) \( \div \) \( \mathrm{ W } \)
= \( \mathrm{ s } \)
= \( \mathrm{ s } \)
