As a teacher of the Work Shop Course at AU Herning I made the WSC toolkit application.WSC toolkit gives basic information about basic electronic components and it includes calculators for most of the different topics.
With WSC TOOLKIT you'll be able to:
Learn about Ohm's law
Learn about resistors
Learn about diodes
Learn about capacitors
Learn about Inductors
Learn about first order filters
Learn about the BJT transistor
Learn about the OPAMP
Learn about the Oscilloscope
Learn about the Multimeter
Calculate voltage, current, ohm, power with the circle of Ohm's.
Calculate the size of resistors based on their colors.
Calculate the resulting resistor of resistors in parallel and series.
Calculate the resulting capacitor of capacitors in parallel and series.
Calculate the resulting inductor of inductors in parallel and series.
Calculate first order filter components based on cut-off frequencies or components.
Calculate the base resistor for BJT transistor used as a switch.
Calculate the resistors used in a BJT amplifier.
Calculate the amplification of an OPAMP amplifier or the components needed for a specific amplification.
Calculate the width of PCB traces
