INTRODUCTION TO ELECTRONICS: Thevenin’s Theorem and Equivalent Circuits

In the diagram below, a circuit is placed within a box. Next, the circuit is opened on the opposite end of the voltage source inside so that two output terminals are visible. The current ( I ) and potential difference ( V ) in relation to the newly created output terminals is then measured: TheContinue reading “INTRODUCTION TO ELECTRONICS: Thevenin’s Theorem and Equivalent Circuits“

INTRODUCTION TO ELECTRONICS: Two-Resistor Current Divider Derivation

We have previously seen how parallel circuits with two resistors ( R ) may be added together using specialized techniques. In one such case, the resistors had equal values, and in other cases, the values differed. These resistance values were then used to ascertain how currents ( I ) divide along each branch of theContinue reading “INTRODUCTION TO ELECTRONICS: Two-Resistor Current Divider Derivation“

INTRODUCTION TO ELECTRONICS: The Current-Divider Formula

As we have seen, the voltage ( V ) drops that occur across resistors ( R ) in parallel circuits are equal in magnitude to the voltage of the source. In addition to this, the currents ( I ) within parallel circuits split apart ( and later recombine ) at nodes. The magnitude of theContinue reading “INTRODUCTION TO ELECTRONICS: The Current-Divider Formula“

INTRODUCTION TO ELECTRONICS: Parallel Circuits

We have previously seen how all of the current ( I ) within a series circuit will pass through each resistor ( R ) situated within it. The sum of the energy drops that a coulomb ( C ) of charge loses as it traverses a circuit is equal to the voltage ( V )Continue reading “INTRODUCTION TO ELECTRONICS: Parallel Circuits“
