Figure 1–5 shows a circuit formed by interconnecting five devices, each of which has two terminals. A voltage and current variable has been assigned to each device using the passive sign convention. The working variables for each device are observed to be as follows: 

(a) Find the missing variable for each device and state whether the device is absorbing or delivering power.

(b) Check your work by showing that the sum of the device powers is zero.
