alleryStart learning →The junction rule equates the sum of all currents entering a junction to the sum of all currents:
AReflected back again
BLeaving the junction
CStored in the junction
DLost inside the wire
Answer & Solution
Correct answer: B. Leaving the junction
1. Charge cannot pile up at a junction.
2. Charge conservation is applied as conservation of current.
3. The sum of all currents entering a junction equals the sum of all currents leaving it.
4. That statement is the junction rule.
