Resistor values are selected after analysis for a given application. For most of the regular circuits, 1/4W resistors with ±5% tolerance carbon composition or carbon film resistors are used. However, ...

Delve into the fascinating world of resistors, a key component in nearly every electronic device we use today. Resistors are crucial for controlling the flow of electrical current in a circuit ...

The previous tutorials featured resistors in direct current (DC) circuits wherein the voltage and current have been assumed to be of constant polarity, flow and direction. The voltage, current and ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...

resistors control current and protect components in electronic circuits. the coloured bands on a resistor is a colour coding system used to identify resistor values and tolerance levels (5% and 10%).

He also experimentally verifies and elucidates on the purpose of each. The resistor does nothing by itself, it’s there to protect the diodes. The diodes are there to protect the MOSFET.

Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.
