Why series springs behave like parallel? A comparison between parallel resistance and series spring.
I know that equation for parallel resistance is
$$\frac{1}{r_{tot}}=\sum_i \frac{1}{r_i}$$
But i wonder to see equation of series spring constant. If we add multiple spring in series. Then their total spring constant is
$$\frac{1}{k_{tot}}=\sum_i \frac{1}{k_i}$$
Why series spring is behaving like parallel?
