Explain the behaviour of a capacitor in an RC circuit when connected to a DC voltage source. How does the voltage across the capacitor change over time? Provide a detailed explanation.

When a capacitor is connected in an RC circuit to a DC voltage source, it initially acts as an open circuit due to its inability to conduct DC current. As a result, the capacitor begins to charge up gradually. The voltage across the capacitor increases exponentially towards the applied voltage of the source. This charging process follows a time-dependent behaviour known as the exponential charging curve. As time passes, the voltage across the capacitor approaches the value of the applied voltage, and the rate of change decreases until it reaches a steady-state condition.
