A voltage source, V, supplying 100 V, is connected to two resistors R1, with a resistance of 400Ω, and R2, with a resistance of 550Ω.  R1 and R2 are in series.  The voltage source has an internal resistance Ri, which is equal to 50Ω. Draw and annotate an electrical circuit model for this circuit. Use, as a minimum, V, I, R1, R2 and Ri to annotate your diagram. Find the current, I, that flows through the circuit, in Amps. Find the voltage drops across the resistors R1 and R2, in Volts.
