When ideal voltage source and ideal current source are connected in series?
Therefore, we can say that when an ideal constant current source is connected in series with an ideal constant voltage source, considering together the combination will be a constant current source.
What is the voltage across an ideal current source?
Voltage sources The voltage across an ideal voltage source is independent of the current flowing through it. An ideal voltage source can be defined by an equation like this: v = V v = \text V v=Vv, equals, start text, V, end text, for example: v = 1.5 V v = 1.5\,\text V v=1.
Can we connect voltage source and current source in series?
Ideal and practical current sources are represented as shown in the below figure. When an ideal voltage source and an ideal current source in series, the combination has an ideal current sources property. Current in the circuit is independent of any element connected in series to it.
What is ideal current source and ideal voltage source?
The internal resistance of an ideal voltage source is zero; it is able to supply or absorb any amount of current. The current through an ideal voltage source is completely determined by the external circuit….Ideal voltage sources.

Can a current source have a voltage drop?
3 Answers. 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 is the current source and capacitor ideal?
Given that both the current source and capacitor are ideal. If someone says the capacitor will be charging up to its capacity, what is the capacity of this capacitor? The voltage will be increasing over time as the current keeps charging. – The current source will stop charging because it’s maximum output voltage is reached.
Is the voltage of a capacitor equal to the DC supply?
One the capacitor is fully charged, theoretically it will act like an open circuit. As no DC is able to pass, there will be no current flow and the voltage on the capacitor will be equal to the supply. Of course, in real life there will be a small amount of leakage and the voltage will never be exactly equal! Anyhow, to answer the question, yes.
What happens when two ideal voltage sources are connected in series?
If two ideal voltage sources are connected in series oposing, i.e., with (+) to (+) and (-) to (-) connections and they both have the exact same rated voltage, then the current will be zero. If their rated voltages are different, then the current will be infinite in the direction of the larger voltage.
When does the current stop charging the capacitor?
The voltage will be increasing over time as the current keeps charging. – The current source will stop charging because it’s maximum output voltage is reached. – The capacitor has reached it’s maximum voltage and will break. Ideal? For ever.
