Problem P. 4605. (February 2014)

P. 4605. The terminal voltages of the power supplies shown in the figure are constant, and the values of the terminal voltage are: U1=15 V and U2=45 V. The resistances of the resistors are R1=10 \Omega and R2=20 \Omega.

a) What are the readings shown by the meters, which are considered ideal?

b) Solve the problem, if the two meters are swapped over.
