In the circuit above, the current through the load (here
represented by the resistor RLoad) is controlled by the input
voltage V1. For V1 = +2V w.r.t. 0V as
shown, find the magnitude and direction of the current in all
branches as well as the magnitude and polarity of the voltage
across each resistor. Assume hfe for
Q1 is 100. If the input voltage is increased to + 8V w.r.t. 0V,
what is the magnitude of the current through the load? Justify your
answers in detail.
Assume all components are ideal.
