For the circuit shown below

1. Power absorbed by the dependent source is 80W
2. Power delivered by the dependent source is 80W
3. Power absorbed by the Independent source is 80W
4. Power delivered by the Independent source is 80W

The given circuit

Let the current supplied by the Independent voltage source is I.
KVL in the loop

20– 5 I– 5		I +	V₁		= 0
			5

or 20 – 10 I – 5 ×	V₁	= 0
	5

or I =	20 – V₁
	10

or I =	20 – 20	= 0 (since, V₁ = 20V given)
	10

Thus there is no power delivered or absorbed by independent source.
Now, power delivered by the dependent source

=		V₁		²	5 watt
		5

=		20		²	× 5 = 16 × 5 = 80 W
		5
