why the internal resistance of energy source or cell is shown in series for voltage source and in parallel for current source?
thanks.
thanks.
A voltage source is a device that maintains a constant voltage output regardless of the load connected to it. On the other hand, a current source is a device that maintains a constant current output regardless of the load connected to it.
Voltage and current sources are used to power electronic circuits. A voltage source provides a potential difference that allows charges to flow through a circuit, while a current source provides a constant flow of charges. Both sources are necessary for a circuit to function properly.
In theory, yes. A voltage source can be designed to provide a constant current output, and a current source can be designed to provide a constant voltage output. However, in practice, it is difficult to achieve perfect constant output with either source.
Some common examples of voltage sources include batteries, power supplies, and generators. Current sources include solar cells, transistors, and specialized electronic circuits.
Ohm's Law states that the voltage across a resistor is directly proportional to the current flowing through the resistor, with the proportionality constant being the resistance. Voltage and current sources are used to create and maintain the voltage and current in a circuit, allowing Ohm's Law to be applied.
