None of these statements is true.Enter a single string of letters, in alphabetical order ("abcdef").Answer: A diode is a two-terminal, electronic device made using semiconductors that is designed to prevent current from flowing in a particular direction. The symbol is a triangle pointing in the direction that (positive) current is allowed to flow and a wall preventing (positive) current from flowing in the opposite direction:1:A diode has two modes, "on" and "off". When "on", current flows, and when "off", no current flows. We generally view diodes as either "ideal" or "modeled", as described below."Ideal" view of a diode+The "ideal" diode is either a short circuit or an open circuit. Specifically, when the voltage across its terminals is negative, no current flows, and when current flows, there is zero voltage across its terminals, as pictured below:Diode"Modeled" view of a diode+51DiodeVIdeal Diode "Off"i=0|+U≤0+ITherefore, with current i and voltage v defined as shown on the left above, for an "ideal" diode:• Current i cannot be negative.Voltage v cannot be positive.. The diode cannot absorb or deliver power.NOTE: The first two statements will change if the current arrow and/or voltage polarity change.Ideal Diode "On"i> 0For a more realistic view of a diode, we replace the short when "on" with a small independent voltage source. When (positive) current is flowing in the direction of the triangle, the diode behaves like a 0.7V source. (Other values of the voltage are possible, but 0.7V is a particularly common value.) When the voltage is less than 0.7V, the diode is "off" and no current flows, as pictured below:Modeled Diode "Off"+v=0Modeled Diode "On"i=0|+IZETTEV < 0.7Vi> 0+V = 0.7VTherefore, again with current i and voltage v defined as shown on the left above, for a "modeled" diode:• Current i cannot be negative.• Voltage v cannot be greater than 0.7V. (It can be negative.)• When "off", the modeled diode absorbs no power. When "on", the modeled diode necessarily absorbs positive power.NOTE: The first two statements will change if the current arrow and/or voltage polarity change.
