Question

Which of the following is the correct equation to calculate electrical energy? P = I/V V = P × I P = I × V E = P × t

Answer 1

You haven't told us what any of those letters represents.

I'm going to assume that ...

-- ' P ' = power

-- ' I ' = circuit current

-- ' V ' = circuit voltage

-- ' E ' = energy

-- ' t ' = time.

Now I'm ready to answer the question that I just invented.

P = I / V

V = P x I

Both of these are false statements, and can't be used to calculate anything.

P = I x V   is the correct equation to calculate electrical power.

E = P x t   is the correct equation to calculate electrical energy.
