Concept:
Dependent source:
A dependent source is a current or voltage source whose value is not fixed (i.e., independent) but rather which depends on some other circuit current or voltage.
Kirchoff voltage law
Kirchhoff's voltage law states that the algebraic sum of the potential differences in any loop must be equal to zero as: ΣV = 0
Kirchoff current law
It states that at a junction in an electrical circuit, the sum of currents flowing into the junction is equal to the sum of currents flowing out of the junction.
Calculation:
Given:
In loop abcd ,apply KVl
170 -25I - 10 ( I +5I) = 0
170 -25I - 60 I = 0
170 - 85 I = 0
85 I = 170
I = 2 A
