If you perform analog-circuit design, you'll occasionally need to use a resistor with a nonstandard value to produce a particular gain, ratio, or attenuation factor. You can create resistors of ...

Programs calculate 1% and ratio-resistor pairs Selecting the best resistor technology for the application Five questions about resistors Resistor Noise—reviewing basics, plus a Fun Quiz The hidden ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, ... the current through each resistor is the same.

It covers how to connect the circuit and then how to calculate the values used in the circuit. ... (C1 & C2) and 1 small resistor (R1), and is added to the VR circuit as shown below. It is important ...

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.

To calculate resistor values, we need to use Kirchhoff's Law: The sum of currents into a node is zero. Considering the node at the junction of the three resistors, we can write: (V IN - V AD )/R1 ...
