Adding a tap to a series circuit alters the untapped voltage ( V ) output across the resistor ( R ) downstream of it. We will now expand our studies to be inclusive of multi-tap voltage-divider circuits. The objective is to determine the magnitude of the bleeder current ( I3 ) flowing through the lowermostContinue reading “INTRODUCTION TO ELECTRONICS: Bleeder Current in Multi-Tap Voltage-Divider Circuits“

INTRODUCTION TO ELECTRONICS: Voltage Dividers With Resistive Loads ( Part 2 )
In a previous exercise, we saw how the addition of a stiff voltage divider to a two-resistor series circuit lowers the voltage ( V ) drop across the lattermost resistor. We are now ready to examine this phenomena with a circuit that contains unequal resistor values: Q: a. What is the unloaded output voltage? b.Continue reading “INTRODUCTION TO ELECTRONICS: Voltage Dividers With Resistive Loads ( Part 2 )“
INTRODUCTION TO ELECTRONICS: Voltage Dividers With Resistive Loads ( Part 1 )
A series circuit that contains two equal-value resistors ( R ) will split the amount of work ( J ) done by the charges equally: Prior to arrival at R1, a coulomb of charged particles ( I ) will contain 10.0 J of energy available to perform work. After passing through R1, the charges willContinue reading “INTRODUCTION TO ELECTRONICS: Voltage Dividers With Resistive Loads ( Part 1 )“
