1.6mm or 14awg
More electricity needed by a cooker requires a thicker cable than for a table lamp.
Speaker cable is used to connect the speaker outputs on audio devices such as a receiver or amplifier to the inputs on the speaker(s).
TRS is the name of the type of connector (e.g. 1/4"/6.3mm jack) and speaker cable is exactly what it is, speaker cable.
Thicker cable loses less thermal energy.
No. As long as the cable is the correct gauge for your speaker load, there is no difference in sound between expensive cable and "zip" cord.
Speaker cable can be used bare or with pin, banana, spade or ring terminals.
Computer speaker cable is twin axial cable used for transferring a signal generated by a computer to speakers for broadcasting sound. Electronics companies such as Maplins sell speaker cable as do third party retailers such as Amazon.
Speaker cable can have an insulator that could be any color. The wire inside is typically silver, copper or gold colored.
No, the speaker has a negative and positive port, they both need to be plugged into for it to work. if they aren't, then the speaker will not create sound
the red cable if there is no red cable usuallly the thicker cable is positive if that does not work look under your vehicle for the starter and fallow the thick wire back to your battery and that is you positive cable.
There are audiophiles who believe that the type and the manufacture of speaker cable is critical to sound quality and they are willing to spend several thousand dollars in some cases to obtain the "best" speaker cable. This answer ignores the audiophile community as they would not seek an answer to the question of speaker cables in a forum such as this. Speaker cable in its basic form is there to pass electrical energy from an amplifier to a speaker. Generally, the bigger the copper cable, the better it will do the job. For that reason, low cost solutions often use mains power cable. A mains flex rated for 20 to 30 amps will work well and will not break the bank. Take a look in hardware stores for an endless supply of mains flex. Alternatively, dedicated speaker cable can be bought in any electronics and hi-fi stores although the cost of speaker cable in stores can be considerably higher than very similar specifications of mains flex.
