A 12V source in a car provides supply to a 42 bulb that is connected to a parallel combination of a 102 bulb and a 52 bulb. The 52 bulb is serially connected to the dashboard bulb with variable resistance, RL. (a) Sketch the circuit diagram (b) sketch the Thevenin equivalent circuit (c) find the maximum value of RL at which maximum power is transferred to the bulb (d) find the value of the maximum power that is delivered to the dashboard bulb (d) If Ri is adjusted in order for maximum power to be transferred, find the percentage of power delivered by the 12V source that reaches RL.
