A dependent source is controlled by other current or voltage in the circuit. There is a current-dependent voltage source on the left branch of the circuit below. This means that the magnitude of the dependent voltage source is a function of the current ib. In this case, the magnitude of the dependent voltage source (in volts) is the magnitude (no units) of the of the current ib divided by 4. What is the value of vg required for the interconnection to be valid? What is the power associated with the current source?
