____________
▪Conduction current ( I ) = dQ/dt ; where Q= charge and t = time, dQ=charge on the body for very short interval of time dt
____________

▪Electricity and Magnetic Effects of Current
Constant current ( I ) = Q/t ; where Q= charge and t= time
____________

▪Current density ( J ) = I/ A ; where I= current and A= area in square meter
__________

▪Electric Power ( P ) = V/I ; where V= voltage and I= current


_________

▪Conductance ( G ) = 1/ R ; where R = resistance of the body
_____________

▪Ohm’s Law = V= IR ; where V= voltage, I = current and R= resistance of the body
_____________


▪Series connection of resistors, Req =( R1+ R2 + R3 +….+ Rn) ; where R1, R2, R3 — Rn are the respective resistances of “n” number of bodies.
______________


▪Parallel connection of resistors, Req = (1/R1 + 1/R2 + 1/R3 +…+ 1/Rn) ; where R1, R2, R3 — Rn are the respective resistances of “n” number of bodies.
