• Since last 30 years, I have been witnessing some problems in students about understanding the theoretically topics.
  • The student can’t draw a circuit properly in his notebook, even by looking at that circuit on the white board, which is already neatly drawn by the teacher.
  • Almost 90% of the students can’t draw the symbols, to the scale, i.e. with correct proportion, even while using ruler.
  • The student can’t recall the symbols of particular components correctly, while drawing the circuit in examination.
  • The student can’t grasp the direction of current flow in the circuit, when battery is connected in it.
  • For even the passive electrical devices, the students sometimes ask naively that whether a switch or resistor or fuse has the polarity i.e. does it have positive negative signs...!!!
  • The student can’t recall the labels of electrodes in semiconductor devices – like anode-cathode of diode & LED, collector-base-emitter of transistor, drain-gate-source of a MOSFET, and large number of other such components which have specific arrangement of electrodes.
  • I was shocked to witness that some of the students who have passed 10th standard with flying colours, could not identify the +ve/-ve signs of a PP3 9V battery or even a pencil cell.
