BASIC ELECTRONICS - OD1633 - LESSON 1/TASK 2
(5) Equivalent Circuits.
In the study of electricity, it is often
necessary to reduce a complex circuit into a simpler form.
Any complex
circuit consisting of resistances can be redrawn (reduced) to a basic
equivalent circuit containing the voltage source and a single resistor
representing total resistance.
This process is called reduction to an
equivalent circuit.
Figure 54 shows a parallel circuit with three resistors of equal value and
the redrawn equivalent circuit. The parallel circuit shown in part A shows
the original circuit.
To create the equivalent circuit, you must first
calculate the equivalent resistance.
Given:
R1 = 45 Ohms
R2 = 45 Ohms
R3 = 45 Ohms
