To solve the question regarding the magnitudes of conduction and displacement currents in a capacitor charged by a DC source when it is fully charged, we can follow these steps: ### Step 1: Understand the Concept of Conduction and Displacement Currents When a capacitor is connected to a DC source, it initially allows current to flow until it becomes fully charged. At this point, the conduction current (I_C) ceases as the capacitor is no longer allowing charge to flow through it. However, there is a concept of displacement current (I_D) that can be considered in the context of changing electric fields. ### Step 2: Analyze the Situation When the Capacitor is Fully Charged When the capacitor is fully charged, the conduction current (I_C) is zero because the capacitor acts as an open circuit. The voltage across the capacitor reaches its maximum value, and no further current flows through the circuit. ...
