when does the current flow from A to B?

  • A. p is open, q is open, ris closed
  • B. p is closed, q is open, ris closed
  • C. p is closed, q is closed, ris open
  • D. p is open, q is closed, ris closed

Step-by-step solution

Current flows from A to B when the path through p and q is closed and the shunt r is open. Option C satisfies this: p and q are closed, forming a continuous path, while r is open, preventing a short circuit.
