Common Questions
What does an ohm measure?
An ohm measures electrical resistance: how strongly a component or path resists current flow. It does not by itself state current, voltage, or power.
Can ohms be converted directly to amps?
Not without voltage and circuit conditions. In a simple DC circuit, current equals voltage divided by resistance.
Is speaker impedance the same as DC resistance?
No. Speaker impedance changes with frequency. The ohm value printed on a speaker is a nominal impedance, not a single fixed resistance at all conditions.
Can resistance alone predict heat?
No. Heating depends on current or voltage as well. Power can be calculated only when enough circuit information is known.
