\( E \)

= \( P t \)

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

=   \( \mathrm{ J } \)

=   \( \mathrm{ J } \)   (to significant figures)


\( P \)

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

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

=   \( \mathrm{ W } \)

=   \( \mathrm{ W } \)   (to significant figures)


\( t \)

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

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

=   \( \mathrm{ s } \)

=   \( \mathrm{ s } \)   (to significant figures)
