Physics at Dr. Sandhya Classes is taught personally by Dr. Sandhya, Ph.D. in Physics, teaching since 2015 — offline in Zirakpur (Highland Marg & Lohgarh Road) and online across India. About Dr. Sandhya
Field lines build intuition
Sketching field lines helps predict forces and potential before calculating anything.
Gauss's law with symmetry
Gauss's law is powerful only when symmetry lets you choose a convenient surface.
Potential and energy
Potential is a scalar, so adding contributions is easier than adding fields.
Capacitors
Practise series and parallel combinations, dielectrics and energy stored — common in boards, JEE and NEET.
