With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

Find the voltage v1 and the currents I1 and I2 for the circuit shown. To solve this problem first find the total current going through the 14 ohm resistor. To do this find the effective resistance of ...

Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...
