What is the total resistance in a series circuit composed of three resistors, $R_1$, $R_2$, and $R_3$?
What is the total resistance in a series circuit composed of three resistors, $R_1$, $R_2$, and $R_3$?
- $R = I_1 + I_2 + I_3$
- $R = rac{1}{R_1} + rac{1}{R_2} + rac{1}{R_3}$
- $R = R_1 R_2 R_3$
- $R = R_1 + R_2 + R_3$ (correct)
