Calculate the power delivered by the 50V source.(a) 274W(b) 276W(c) 285W(d) 291WI got this question in a job interview.This key question is from Source Transformations topic in portion Techniques of Circuit Analysis of Electric Circuits

Answer»

The correct option is (a) 274W

For explanation I WOULD say: By using source transformation the above network is REDUCED and current in the circuit is found out and later power delivered by 50V source= 50*current in the circuit= 50*5.48A= 274W.
