What is Norton theorem with example?
Nortons Theorem states that “Any linear circuit containing several energy sources and resistances can be replaced by a single Constant Current generator in parallel with a Single Resistor“.
How do you calculate current using Norton’s Theorem?
Steps to Analyze an Electric Circuit using Norton’s Theorem Calculate / measure the Short Circuit Current. This is the Norton Current (IN). Open Current Sources, Short Voltage Sources and Open Load Resistor. Calculate /measure the Open Circuit Resistance.
How Norton’s Theorem is equivalent to Thevenin’s Theorem?
Thevenin and Norton’s resistances are equal. Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.
What is a Norton equivalent current?
It states that any two terminal linear network or circuit can be represented with an equivalent network or circuit, which consists of a current source in parallel with a resistor. The current source present in the Norton’s equivalent circuit is called as Norton’s equivalent current or simply Norton’s current IN.
How do you find the equivalent current?
The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3 …
How do you convert Norton’s equivalent circuit into Thevenin’s equivalent circuit?
Thevenin voltage is equal to Norton’s current times Norton resistance. Norton current is equal to Thevenin voltage divided by Thevenin resistance.
How Norton’s theorem is equivalent to Thevenin’s theorem?
Norton’s Thereom is identical to Thevenin’s Theorem except that the equivalent circuit is an independent current source in parallel with an impedance (resistor). Therefore, the Norton equivalent circuit is a source transformation of the Thevenin equivalent circuit.
How do you get Thevenin equivalent circuit from Norton equivalent circuit?

How does Kirchhoff’s law of current work in a circuit?
Kirchhoff’s law of current states that the algebraic sum of all current at any node (or junction) in an electrical circuit is equal to zero or equivalently the sum of the currents flowing into a node is equal to the sum of the currents flowing out of that node. Find current i3 at the node shown below.
How to find the equivalent resistance of Norton’s circuit?
To determine the equivalent resistance of the circuit of figure 1, looking through x-y, the constant source is deactivated as shown in figure 3 (a). Norton’s equivalent circuit has been shown in figure 3 (b). In the circuit of figure 4, if R1 = R2 = 4Ω, find the short circuit current through x-y (use Norton’s theorem).
How to find Rint through a circuit using Norton’s theorem?
This gives Is.c = 0. To find Rint through x-y, let x-y be kept open circuited and a d.c voltage vdc be applied, input current being idc (figure 6 (b)). Find the current through RL in the circuit of figure 7 using Norton’s Theorem.
