Thevenin Theorem

Any linear circuit, no matter how complex, maybe simplified to an equivalent circuit utilizing only a single voltage source and series resistance coupled to a load, according to Thevenin's Theorem. The superposition principle says that all foundational equations must be linear, and the notion of "linear" is still the same (i.e., there should not be any exponentials or roots). This is particularly the case when operating with passive elements like resistors, inductors, and capacitors. However, some components (particularly some gaseous and semiconductor devices like tunnel diode, Schottky diode, transistors like BJT, MOSFET) are nonlinear, meaning their current resistance fluctuates with voltage and current. As a result, circuits made up of these parts are known as nonlinear circuits.

Question

A voltage divider of 50 ohms is 2 points
connected across a 100 V DC
source. A load resistance of 10
ohms is connected across a
tap in the potential divider and
the negative of the source. If a
current of 4 A flows towards
the load, what is the current
supplied by the source?
(Remember, a voltage divider
is a network of resistors that
are connected in series the
purpose of which is to divide a
voltage into each of the
resistors.)

It is common, in the analysis of electrical circuits, to determine voltage drops over resistors specific. If these are passed in circuits formed by independent sources, the principle of superposition is the technique used to solve this problem.
