To linearize the equation $F = \frac{R}{VI}$ for plotting $R$ against $I$, we need to express $R$ as a function of $I$ in the form $Y = mX + c$. Step 1: Start with the given equation. $$F = \frac{R}{VI}$$ Step 2: Rearrange the equation to isolate $R$. Multiply both sides by $VI$. $$R = FVI$$ This equation is already in a linear form $Y = mX + c$, where: • $Y = R$ (the variable to be plotted on the y-axis) • $X = I$ (the variable to be plotted on the x-axis) • $m = FV$ (the slope of the line, assuming $F$ and $V$ are constants) • $c = 0$ (the y-intercept) The linearized equation is: $$\boxed{R = (FV)I}$$ To plot a graph of $R$ against $I$: • Plot $I$ on the x-axis (independent variable). • Plot $R$ on the y-axis (dependent variable). • The equation $R = (FV)I$ represents a straight line. • This line will pass through the origin $(0,0)$ because the y-intercept is $0$. • The slope of this straight line will be $FV$. 3 done, 2 left today.
