Question

question 28
which equation is equivalent to $i = prt$?
\\( \bigcirc \\ p = i + rt \\)
\\( \bigcirc \\ p = irt \\)
\\( \bigcirc \\ p = \frac{i}{rt} \\)
\\( \bigcirc \\ p = i - rt \\)

Explanation:

Step1: Isolate $p$ by dividing both sides

Divide each side of $I = prt$ by $rt$ (where $rt
eq 0$).
$\frac{I}{rt} = \frac{prt}{rt}$

Step2: Simplify the right-hand side

The $rt$ terms cancel out on the right.
$\frac{I}{rt} = p$

Answer:

$\boldsymbol{p = \frac{I}{rt}}$ (the third option)
