Question

Two_Meter_Ideal Rzix +- RED R, |X VM BLACK Ideal AM tIdeal Given: 1. As shown in the diagram, the meters are ideal 2. The meter readings are denoted, V and Iand along with the resistance values: R,, R,, and R, are given in the parameter file Do: a) Find I and the power supplied, P, by the current source. b) Except for R,, use all the same values cited in the "Given" statement, and find the new value of Rwhich will result in the current source, /., supplying zero power when Ig #0 Amps? (It is possible to have a negative value of resistance for R, .) What is the new value, I,, for the current source? Hints: 1. Replace each ideal meter with the equivalent circuit element, i.e. either a short or an open, as appropriate 2. Label the short and open with the meter readings given in the parameter file.
