sevag00 said:Oh ok. 28 not 30. Then Is = 26.5.
sevag00 said:Here's the new sketch. If I'm not wrong then 29.5 A.

A dependent source is an electrical component that is controlled by another voltage or current within the circuit. This means that its output is not determined by its own internal characteristics, but rather by the input from another source.
To find the value of Vx, you will first need to determine the relationship between Vx and the controlling voltage or current. Once this relationship is known, you can use the given values of the controlling source to calculate the value of Vx using Ohm's Law or other circuit analysis methods.
The value of Is in a circuit with a dependent source can be calculated by using Kirchhoff's Current Law (KCL) at the node where the dependent source is connected. This will create an equation with unknown variables, including Is. Solving this equation will give you the value of Is.
The power of a dependent source is the amount of energy it is supplying or absorbing in a circuit. It is calculated by multiplying the voltage or current of the dependent source by the controlling voltage or current, depending on the type of dependent source. The resulting value will have units of watts (W) or volt-amperes (VA).
Yes, a dependent source can have a negative value. This simply means that the source is supplying energy in the opposite direction of the controlling voltage or current. It is important to pay attention to the signs and directions of dependent sources in a circuit, as they can significantly affect the overall behavior and analysis of the circuit.
