Q.Write the steps involved in drawing DC equivalent circuit of an amplifier.

The DC equivalent circuit keeps only the parts that carry direct current, so capacitors and the signal source are removed. …

[!TLDR]

Open all capacitors, remove the signal source, keep $V_{CC}$ and the resistors.

The DC equivalent circuit is used to find the operating point, so it must show only the direct-current paths. Because a capacitor blocks DC, every coupling and bypass capacitor is replaced by an open circuit. The AC signal source plays no part in biasing and is removed. Everything that carries DC — the supply $V_{CC}$ and all biasing resistors together with the transistor — is retained, giving the DC equivalent circui …
