Write the equation for the equivalent resistance of $n$ resistors connected in series and the equation for the equivalent resistance of $n$ resistors connected in parallel.
(N/A) For $n$ resistors with resistances $R_1, R_2, R_3, ..., R_n$ connected in series,the equivalent resistance $R_s$ is the sum of individual resistances:
$R_s = R_1 + R_2 + R_3 + ... + R_n$
For $n$ resistors with resistances $R_1, R_2, R_3, ..., R_n$ connected in parallel,the reciprocal of the equivalent resistance $R_p$ is the sum of the reciprocals of individual resistances:
$\frac{1}{R_p} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + ... + \frac{1}{R_n}$
$R_s = R_1 + R_2 + R_3 + ... + R_n$
For $n$ resistors with resistances $R_1, R_2, R_3, ..., R_n$ connected in parallel,the reciprocal of the equivalent resistance $R_p$ is the sum of the reciprocals of individual resistances:
$\frac{1}{R_p} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + ... + \frac{1}{R_n}$
