For the circuit shown in Figure P5.55, let \(\beta=100\).

(a) Find \(R_{T H}\) and \(V_{T H}\) for the base circuit.

(b) Determine \(I_{C Q}\) and \(V_{C E Q}\).

(c) Draw the load line and plot the \(Q\)-point.

(d) If the resistors \(R_{C}\) and \(R_{E}\) vary by \(\pm 5\) percent, determine the range in \(I_{C Q}\) and \(V_{C E Q}\). Draw the load lines corresponding to the maximum and minimum resistor values and plot the \(Q\)-points.
