Most sources of electrical power behave as (approximately) ideal voltage sources In this case, if we have several loads that we want to operate independently, we place the loads in parallel with a switch in series with each load Thereupon, we can switch each load on or off without affecting the power delivered to the other loads. How would we connect the loads and switches if the source is an ideal independent current source? Draw the diagram of the current source and three loads with on-off switches such that each load can be switched on or off without affecting the power supplied to the other loads. To turn a load off, should the corresponding switch be opened or closed? Explain.

The diagram shows an ideal (zero internal resistance) DC source connected to three identical resitances and a switch. In the diagram, the switch is open. If initially, the switch is open, what happens to current I1 and I2 after the switch is closed?
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.
a)Draw and annotate an electrical circuit model for this circuit. Use, as a minimum, V, I, R1, R2 and Ri to annotate your diagram.
b)Find the current, I, that flows through the circuit, in Amps.
c) Find the voltage drops across the resistors R1 and R2, in Volts.
