Final answer:
The correct answer, based on standard equations in Physics and after correcting a typo in the original formula, is R = V²/P, where V represents voltage and P represents power. This expression is derived using Ohm's law and the power equation. So the correct answer D. R= P/V.
Step-by-step explanation:
To solve for resistance (R) from the given formula P = I/E, we need to correct a typo in the original formula, where E likely represents voltage (V) and I represents current. Since power (P) is actually the product of current (I) and voltage (V), the correct formula is P = IV.
Using Ohm's law which states V = IR, we can manipulate these equations to express resistance in terms of power and voltage.
First, let's express current in terms of power and voltage using the power formula:
I = P/V
Now, by substituting into Ohm's law we get:
V = (P/V)R or V² = PR
Solving for R from this equation gives us:
R = V²/P
So the correct answer to solving the formula for resistance is:
R = P/V, which is not listed directly in the options provided, but due to the misunderstanding in the question stemming from the typo, the correct formulation based on standard electrical equations from Physics is as shown above.
