Answer 1

Dicktionary will help you.

Answer 2

An Ohm is a measurement of electrical resistance. 0-5 Ohms are considered a dead short in construction. The less the resistance, the more current will flow for a given voltage. An open (disconnected) will measure close to 1 million Ohms or Mega (M) or a meter will show 'OL'.

In the case of speakers and amplifiers. You want the resistance (Ohm) of the speaker to be equal to the resistance of the Amplifier. When the resistances are equal, maximum power is transferred.

Answer 3

Ohm is the measure of how MUCH resistance your speaker provide to voltage (stereo).

With no resistance, you would create a SHORT circuit and burn out the radio.

The key thing in stereo is that you get the OHM that is recommended for your stereo (amplifier).

Good Luck.
