Resistors aren’t resistors – at high frequencies, that is. Many designers don’t realize that parasitic elements in real components affect their values. When frequencies reach hundreds of megahertz, ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...

Introductory courses on noise in electronic circuits often start by stating the following formula for the open-circuit noise voltage of a resistor: You’ll probably argue that’s a lot of conditions; ...

The following resistor network is set up. Calculate the total resistance of the network. This means that the three individual resistors can be replaced by one resistor of \({3.27}\Omega\). Adding ...

There are times when you might want an odd-value resistor. Rather than run out to the store to buy a 3,140 Ω resistor, you can get there with a good ohmmeter and a willingness to solder things in ...
