Question

a string of fifty 15 ohm christmas tree lights are connected in series. one burns out, they all burn out. calculate the total resistance.

Answer 1

The total resistance is 750 [ohm]

Step-by-step explanation:

To solve this problem we must remember that when we have resistors connected in series, these are added each by the resistance value, in this way we have:

Rt = 15 * 50 = 750 [ohm]
