Suppose a $$220\mathrm{V}$$ resistor is incorrectly installed in the R7 position of the amplifier in Figure 1. What effect does this have on the circuit? The connection from R1 to the supply voltage V1 in Figure 1 has opened. (a) What happens to Q1? (b) What is the de voltage at the Q1 collector? (c) What is the de voltage at the Q2 collector?
