is ignition coil and coil pack the same thing
Ignition coil Where coils are individually applied per cylinder, they may all be contained in a single molded block with multiple high-tension terminals. This is commonly called a coil-pack.
Cigarette lighter receptacle The lighter is a metal or plastic cylinder containing a thin flat coil of nichrome metal strip, through which high current (~10 amperes) passes when the device is activated, usually by pushing it into the socket as though it were a push-button. When pushed in, the lighter is held against the force of a spring by a clip attached to a bi-metallic strip.[4] The heating element glows orange hot in seconds, causing the bi-metallic strip to bend and release the mechanism, and the handle pops out, eliminating the need for the smoker to time the heating operation. If the lighter is then promptly removed from its socket, it can light a cigarette, cigar, or tinder.
