The four types of tissue in the human body: A tissue is a group of cells that is from similar embryological origin and is specialized for a particular function. Four types: epithelial, connective, muscle and nervous.

You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention.
In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. For a bias less than the PIV, the reverse current is very small. 2  For a normal PâN rectifier diode, the reverse current through the device in the micro-ampere (ÂµA) range. 3  However, this is temperature dependent, and at sufficiently high temperatures, a substantial amount of reverse current can be observed (mA or more).
