Norton Current Formula:
| From: | To: |
Norton current (IN) is a fundamental concept in circuit analysis that represents the short-circuit current in Norton's theorem. It is used to simplify complex linear circuits into an equivalent current source in parallel with a resistance.
The calculator uses the Norton current formula:
Where:
Explanation: The Norton current is calculated by dividing the Thevenin voltage by the Thevenin resistance of the circuit.
Details: Norton current calculation is essential for circuit analysis and design, allowing engineers to simplify complex networks and analyze circuit behavior more efficiently.
Tips: Enter Thevenin voltage in volts, Thevenin resistance in ohms. Both values must be positive numbers greater than zero.
Q1: What is the relationship between Norton and Thevenin equivalents?
A: Norton and Thevenin equivalents are duals of each other. A Thevenin equivalent consists of a voltage source in series with a resistance, while a Norton equivalent consists of a current source in parallel with a resistance.
Q2: When should I use Norton's theorem?
A: Norton's theorem is particularly useful when analyzing circuits with multiple current sources or when dealing with parallel circuit configurations.
Q3: Can Norton's theorem be applied to non-linear circuits?
A: No, Norton's theorem applies only to linear circuits containing independent sources, dependent sources, and linear elements.
Q4: How do I find Thevenin voltage and resistance?
A: Thevenin voltage is the open-circuit voltage at the terminals, and Thevenin resistance is the equivalent resistance seen from the terminals with all independent sources turned off.
Q5: What are the limitations of Norton's theorem?
A: Norton's theorem cannot be applied to circuits containing non-linear elements, and it assumes the circuit is linear and bilateral.
