A practical voltage source can also be represented as
Right Answer is:
Resistance in series with an ideal voltage source
SOLUTION
Practical voltage Sources
A practical voltage source is shown as an ideal voltage source in series with a resistance. This resistance is called the internal resistance of the source, as shown in Fig.
A practical voltage source, such as a battery, has drooping load characteristics due to some internal resistance. The terminal voltage falls as the current increases due to its internal resistance. A voltage source has small internal resistance in series.
