Step 1
Voltage Is Set
The source fixes the potential difference between its terminals.
Circuit Element Explanation
Independent Voltage Source
A voltage source gives the circuit a fixed electrical push between two points.
Back to Circuit ElementsExplanation
- It sets the voltage level that drives charge through the circuit.
- It is used as a battery, supply rail, or input signal source.
- It tries to maintain its voltage even when the connected load changes.
Formula
V = constant
- The source tries to keep the same voltage across its terminals.
Key Idea
A voltage source maintains a set voltage and pushes charge through the path.
Visual Explanation Steps
Show a battery creating a pressure-like push that sends current dots around the loop.
Step 2
Electrical Push Appears
The green push arrow shows the source driving charges through the circuit.
Step 3
Load Current Changes
When load resistance changes, the current changes according to the connected circuit.
Step 4
Voltage Stays Fixed
Even when current changes, the ideal source maintains the same terminal voltage.
