Applications of Exponential and Power Equations

Applications of Exponential and Power Equations. Lesson 5.4. You may have noticed that many equations can be solved by undoing the order of operations. This strategy also applies for more complex power equations that arise in real-world problems. EXAMPLE A.

You will need to read the section on power, do the assigned problems so that you are an expert.

You will need to read the section on power, do the assigned problems so that you are an expert. Also be able to derive the expressions for power from ohms law. P = work/time = Vq/t = VI because I = q/t Then just substitute from R = V/I
