Calculate the power absorbed by each element in the circuit

Calculate the power absorbed by each element in the circuit in Fig. P1.45. Also, verify that Tellegen\'s theorem is satisfied by this circuit.

Solution

Ans)

Power absorbed by element 1----V*I=5*5= 25 W

Power absorbed by element 2----V*I=5*1= 5 W

Power absorbed by element 3----V*I=10*4= 40 W

Power absorbed by element 4----V*I=-5*3= -15 W

Power absorbed by element 5----V*I=10*1= 10 W

Power absorbed by element 40 V source----V*I=-40*5=-200 W

Power absorbed by element 4 A source----V*I=30*4= 120 W

Power absorbed by element 15 V source----V*I=15*1= 15 W

According to tellegen\'s theorem algebraic sum of all the powers in a circuit should be zero

i.e 25+5+40-15+10-200+120+15=0 so tellegen\'s theorem is verified and circuit satisfies it
