Answer to Question #187341 in Electric Circuits for Alexandra Spiridon

Question

The scheme of an electrical circuit is represented in the figure. The three resistors are identical, having the electrical resistance R = 60 and an ideal amperemeter A (Ra=0)

The Ampermeter A. indicates the value I = 1A when the K switch is open and the value I'=1,3A when the switch k is closed. Determine:

a. Value of the equivalent resistance of the source outer circuit when the k switch is

closed;

b. The value of inner resistance r of the generator;

c. Electromotive voltage value E. of the generator;

d. The voltage value indicated by an ideal voltmeter (RV → ) mounted instead of the switch.
