DC circuitsQuestion 196 of 1506

A series circuit has a corroded connection with high resistance. What happens to the voltage at the load?

  1. It rises above the source voltage
  2. It drops, so the load may not work well
  3. It stays exactly the same
  4. It reverses polarity
Show answer

Correct answer: It drops, so the load may not work well

The bad connection uses up part of the voltage, so less is left for the load.
