Concept

# Problem: A) Rank the circuits based on the current through the battery immediately after the switch is closed. Rank from largest to smallest. To rank items as equivalent, overlap them.B) Rank the circuits based on the current through the battery a very long time after the switch is closed. Rank from largest to smallest. To rank items as equivalent, overlap them. C) Rank the transformers on the basis of their rms secondary voltage. Rank from largest to smallest. To rank items as equivalent, overlap them.

###### FREE Expert Solution

A) The inductor has infinite resistance (open circuit) at the instance the switch is closed. Place gaps where the inductors are then rank the remaining resistors.

Parallel resistors have the highest current, while series resistors have the least current.
