Find the power factor of scenarios $1,2,3$ and $4$ and which of them is from the point of view of both the consumer and the manufacturer

please interpret in detail that this is the most efficient scenario.

In scenario $5,$ in order for the load connected to the network to be fully resistive, what characteristics of a capacity instead of the C$2$ capacity

should it be added?

Scenario $1$: Switches S$1,$ S$2$ and S$3$ are off, S$4$ and S$5$ are on$.$

Scenario $2$: Switches S$1,$ S$2,$ S$3$ and S$4$ are off, S$5$ is on$.$

Scenario $3$: The S$1,$ S$2,$ S$3,$ S$4$ and S$5$ switches are turned off.

Scenario $4$: S$1$ and S$2$ are on$,$ S$3,$ S$4$ and S$5$ switches are off.

Scenario $5$: The S$1,$ S$2,$ S$3,$ S$4$ and S$5$ switches are turned off.
