Thevenin's Theorem:
Thevenin's theorem allows us to determine the equivalent resistance of a circuit connected in a closed loop by isolating the external variables. In simpler terms, it tells us that the equivalent resistance of a circuit is equal to the resistance of the internal circuit, plus the resistance of the external circuit connected to it.
Norton's Theorem:
On the other hand, Norton's theorem helps us to determine the current flowing through a circuit by isolating the external variables. It states that the current flowing through a closed loop is equal to the current flowing through each independent branch in the loop, divided by the total resistance of the loop.
Examples:
Consider a circuit with a battery (V), a resistor (R), and a variable current source. According to Thevenin's theorem, the equivalent resistance is equal to R, since the external battery is isolated.
In another example, consider a circuit with multiple branches connected to a single power source. According to Norton's theorem, the current flowing through each branch is equal to the current flowing through the entire circuit, since the external power source is isolated
