A lower-voltage source is connected in parallel with a higher-voltage source. What does the lower-voltage source do?

  1. It carries more than its share of the load
  2. It acts as a load instead of sharing the load current
  3. It raises the voltage of the other source
  4. It has no effect on the circuit
Show answer

Correct answer: It acts as a load instead of sharing the load current

The higher-voltage source drives current into the lower-voltage one.
