It seems like the frequency response is always 20Hz-20kHz, everything seems to have 100 watts or thereabouts, and then there's ohms. What's an ohm? Do you need to match a speaker's ohms to a ...

1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are supposed to resist current. What the heck ...

[Alex Busman]’s first foray in iOS programming looks like a pretty useful tool. He came up with Ohm Sense, an iPhone app that will take a picture of a resistor and calculate the value based on ...

The symbol for resistance is R, it is measured in ohms \((\Omega )\). The symbol for current is I, it is measured in amperes \((A)\).

As their name suggests, Milliohm meters measure resistance in milliohms, a unit of measure that equals 1/1000 of an ohm. Bandwidth is the frequency range for AC current or voltage to be measured.

If the temperature of a metal conductor increases, the ions of the metal vibrate more vigorously. Hence, for a metal, resistance increases with increasing temperature. Often the increase in ...
