The hosts announce a double dose of questions in this episode and will be doubling up on episodes and questions in the coming months until the current technician study guide expires on June 30th, 2026 (0:40-0:52, 47:13-49:15).<\/p>\n<p>Key topics and questions covered include:<\/p>\n<p>Resistors<br \/>\nThe electrical component that opposes the flow of current in a DC circuit is a resistor (2:32-3:57).<br \/>\nA potentiometer is often used as an adjustable volume control (5:24-6:20).<br \/>\nThe electrical parameter controlled by a potentiometer is resistance (8:28-9:12).<br \/>\nCapacitors<br \/>\nA capacitor stores energy in an electric field (9:37-10:20).<br \/>\nA capacitor consists of conductive surfaces separated by an insulator (10:48-11:36).<br \/>\nInductors<br \/>\nAn inductor stores energy in a magnetic field (11:51-12:24).<br \/>\nAn inductor is typically constructed as a coil of wire (13:06-13:42).<br \/>\nSwitches<br \/>\nThe function of a single pole double throw (SPDT) switch is that a single circuit is switched between one of two other circuits (13:59-15:01).<br \/>\nComponent three in Figure T2 represents a single pole single throw switch (21:26-22:00).<br \/>\nFuses<br \/>\nA fuse is used to protect other circuit components from current overloads (16:49-17:42).<br \/>\nBatteries<br \/>\nNickel metal hydride, lithium-ion, and lead acid battery chemistries are all rechargeable (17:55-18:56).<br \/>\nCarbon zinc battery chemistry is not rechargeable (19:00-20:52).<br \/>\nDiodes<br \/>\nIt is true that forward voltage drop in a diode is lower in some diode types than in others (28:09-29:30).<br \/>\nA diode allows current to flow in only one direction (30:06-30:52).<br \/>\nThe cathode lead of a semiconductor diode is often marked on the package with a stripe (37:26-38:07).<br \/>\nForward current causes a light-emitting diode (LED) to emit light (38:32-39:37).<br \/>\nThe names for the electrodes of a diode are anode and cathode (41:15-42:18).<br \/>\nTransistors<br \/>\nA transistor can be used as an electronic switch (32:40-33:50).<br \/>\nA transistor can consist of three regions of semiconductor material (34:16-35:02).<br \/>\nAn FET (Field Effect Transistor) has a gate, drain, and a source (35:26-36:24, 40:29-41:00).<br \/>\nA transistor can provide power gain (42:27-43:02).<br \/>\nThe term that describes a device&#8217;s ability to amplify a signal is gain (43:11-43:53).<br \/>\nThe names of the electrodes of a bipolar junction transistor are emitter, base, and collector (43:58-44:46).<\/p>\n<p><a href=\"http:\/\/www.amateurlogic.tv\/downloads.htm\">Download<\/a><br \/>\n<a href=\"https:\/\/youtu.be\/nxAXT4cbsug\" target=\"_blank\" rel=\"noopener noreferrer\">YouTube<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ham College episode 132 is now available for download.
