Where you use thevenins theorem in daily life?
The number of vehicles per hour entering a busy road junction equals the number leaving it The amount of liquid entering a pipe equals the amount issuing from the end, plus the leaks.
You would use the Pythagorean Theorem when you are trying to determine the length of a side on a right triangle. OR You might use the Pythagorean Theorem if you are carpenter or builder. A carpenter might use the Pythagorean Theorem to find the length of the hypotenuse (longest side of the triangle) or the length of the wall or roof. Use can use this methed or theorem in any building situation.
Ohm's Law and Kirchhoff's Laws allow solution of complex circuits, but they do not solve complex supplies. If a supply contains multiple voltages or currents, or multiple resistances (or both), use Thévenin's ("tay-ven-ins") theorem: "Any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent to a single voltage source V and a single series resistor R."
