Can you have a current source in series with a voltage source?

The addition of a voltage source in series has zero effect on the current through those series-connected elements, so you can leave in or take out the voltage source without any effect on the current in the series-connected circuit elements.

What happens if current sources are connected in series?

If two current sources are connected in series, then the source rated for lower current will act upon the circuit. The other source will become redundant. Case 2: If the two voltage sources are connected in parallel, then the source rated for higher voltage will act upon the circuit.

Can you combine dependent and independent current sources?

Current sources are not allowed to be connected together in series, either of the same value or ones with different values.

What happens when more than one voltage source is added to a circuit in series?

When more than one voltage source is used, they can be connected either in series or in parallel, similar to resistors in a circuit. When voltage sources are in series facing the same direction, their internal resistances add and their electromotive force, or emf, add algebraically.

Does an independent current source have a voltage?

An “independent” current source will generate sufficient voltage to maintain its desired value of current flowing within the circuit to which it is connected.

What is dependent and independent voltage source?

Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.

Does voltage change over a current source?

An ideal current source generates a current that is independent of the voltage changes across it. An independent current source with zero current is identical to an ideal open circuit. The voltage across an ideal current source is completely determined by the circuit it is connected to.

Does a current source affect voltage?

A current source can certainly have a voltage across it. If the voltage across a current source is zero, then it is not delivering or absorbing any power. However, if the voltage across the source is not zero, then it is either sourcing or sinking power into the rest of the circuit.

How does voltage affect current?

The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.

What is the difference between an independent voltage and current source?

An independent voltage source (sometimes called an ideal voltage source), always outputs a constant voltage, regardless of what happens elsewhere in the circuit. The same idea applies to an independent current source, where the current output is always the same value regardless of the voltage drop elsewhere in the circuit.

How can we combine series independent voltage sources and series resistors?

We can now combine the series independent voltage sources and the series resistors into single equivalent elements: how can we add two voltage source by resistors combining positive and negative voltage sources in series independent current and voltage sources in series

What are dependent sources in a circuit?

Sometimes, there are things like dependent sources, or sources that change their output depending on other parts of the circuit. Their symbols look like this: On occasion, such as with a current mirror, a power source in real life depends on the voltage or current in another portion of the circuit.

How many ideal voltage sources can be connected in series?

Thus, the series connection of two ideal voltage sources is equivalent to a single independent voltage source given by: Clearly, the obvious generalization to N voltage sources in series holds. In a previous example we determined the current i in the one-loop circuit shown below:
