If there’s one thing that will surely blind us, its reading resistor color bands. It doesn’t help that red looks exactly like orange, brown and black are indistinguishable, and different component ...

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 ...

Electronics takes a lot of math. Once you’ve mastered all the algebra and calculus, though, it is sometimes a drag to go through the motions. It also can be error-prone. But these days, you have ...

Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...
