Hi! I am Abu. I did my MSc in Optical Engineering. I have experiences with opto-electronic device like, solar cells, LEDs, lasers. I have two years of teaching experience in basic electrical engineering and machines. I have 7+ years of working experience in semiconductor device. I like to teach and interact with students. See you in classroom. The courses I like to teach:1) Electrical Circuits:DC circuits: KCL, KVL, Norton, Thevenin theorems, mesh- super mesh analysis, Nodal analysis. AC circuits: Impedance, reactance, power factor, series- parallel circuits, transformer2) Transient analysis: RC, RL, RLC circuits3) Filter circuit: low pass, high pass, bandpass, bandstop filter circuit4) Op-amp: solving the circuit to find gain and other circuit parameters5) Semiconductor (electronics):PN junction, rectifier diode, zener diode, full wave rectifier circuit, half wave rectifier circuit, thyristor (SCR), PNP or, NPN junction, transistor analysis, MOSFET, JFET6) Circuit simulation: SPICE, Multisim7) solar cells, LED8) electrical machines (AC & DC)9) Digital circuit: truth table, AND-OR, NAND, NOR, EX-OR, EX-NOR gates, decoder, multiplex, mealy-moore`s theorem, Boolean algebra, binary to decimal to hex and other conversion or, vice versa. 2`s complement, binary addition, subtraction, division, multiplication, D- flipflop, T-flipflop, adder circuit, K-map theory , Dmux etc.**Note: to solve exercise problems, assignments; I usually charge more. Because, it requires more effort. Thank you!
