4Ω 3Ω VB 1Ω VA EV + 16V

Problem #20) Given the following circuit having the component values: Vs = 50 volts, R₁ = 25 2, R₂ = 50 92, Vs A a) Determine the node voltages VÀ and Vв in the circuit as well as the source current Is. b) If the resistor R₂ is removed from the circuit and replaced by an idea wire (short-circuit), determine the new values for VA, VB, and Is. Is R1 R2 B a) VA = VB = Is = b) VA = VB = Is = E E 3 (V) (A)

Ideal voltage sources and ideal current sources, while both being sources of electrical power, behave very differently from one another. Voltage sources Current sources V Explain how each type of electrical source would behave if connected to a variable- resistance load. As this variable resistance was increased and decreased, how would each type of source respond?
