A sudden increase in the total current into a parallel circuit may indicate______________?

Correct answer: C. an increase in source voltage

  • A. a drop in source voltage
  • B. an open resistor
  • C. an increase in source voltage
  • D. either a drop in source voltage or an open resistor

Explanation

For a fixed parallel network, total current increases when the source voltage increases, since I = V/Rt. A dropped voltage or an open branch would instead reduce the total current.
