Is independent voltage source linear?
“Linear” is a term that applies to a system with inputs and outputs, since it describes a particular kind of relationship between them. This means that simple voltage and current sources (when seen as ideal circuit elements) are neither linear nor non-linear.
Are voltage and current independent of each other?
Remember that voltage can exist without current. A battery is the most common voltage source for a circuit with the voltage that appears across the positive and negative terminals of the source being called the terminal voltage.
What is independent voltage and current source?
An independent voltage/current source is an idealized circuit component that fixes the voltage or current in a branch, respectively, to a specified value. Remember that the state of a circuit is given by the voltage across and current through each branch of the circuit.
Does a voltage source have current?
The current through an ideal voltage source is completely determined by the external circuit. When connected to an open circuit, there is zero current and thus zero power….Ideal voltage sources.

Does voltage source produce current?
A voltage source generates a potential difference across its two terminals. When these two terminals are joined to a network of interconnected components that form a continuous conductive path, current will flow. Simple electric circuits often consist of one voltage source connected to a few components.
Is voltage dependent on current?
Both are true. The voltage measured across a particular resistor depends upon the amount of current (amps) flowing thru it. But the amount of current depends on the voltage (pressure) on the circuit containing the resistor.
What is a linear electrical circuit?
Informally, a linear circuit is one in which the electronic components’ values (such as resistance, capacitance, inductance, gain, etc.) do not change with the level of voltage or current in the circuit. Linear circuits are important because they can amplify and process electronic signals without distortion.
Does a circuit need a voltage source?
An Ideal current source will produce whatever voltage is necessary to permit it to deliver its specified current. An ideal voltage source will deliver whatever current the rest of the circuit requires when it is delivering its specified voltage.
