Expert Solution

Step 1

Since you have asked multipart questions, we will answer you the first three parts of the question. Kindly repost the question with parts to be solved.

When resistors are connected in series the total resistance is given as,

$R_{t o t a l} = R 1 + R 2 + R 3 + . . . . .$

When resistors are connected in parallel the total resistance is given as,

$\frac{1}{R_{t o t a l}} = \frac{1}{R 1} + \frac{1}{R 2} + \frac{1}{R 3} + . . . . .$
