These proteins are also part of the immune system (immunoglobulins), help blood to clot (clotting factors), maintain pH balance, and are enzymes involved in chemical reactions throughout the body. Electrolytes are another large category of substances dissolved in plasma. They include:
An ideal op amp has infinite gain (), infinite input resistance ( ), and zero output resistance (). You should use these two assumptions to analyze the op amp circuits covered in the assignments below.
Because the amplifier is an active electronic device, it needs power, and so you have to put any active speakers near a power outlet. For most audio systems, the subwoofer is probably going to be your only active speaker (though you can also find passive subwoofers, and some high-end audio systems use these). Thereâs no practical reason for any of your other speakers to be active.
