Question

write all formules of electricity chapter and deriviation of all ch electricity

Answer 1

(1) R =V/I
(2) I =Q/T
(3) H=IRT
(4)Req =R1+R2+R3...Rn

Answer 2

The formulas used in class X are-
1- I,current=Q,charge/T,time
2- V,potential differnce=W,work done/Q,charge
3-V,potential difference=I,current*R,resistance
4-Resisitivity=(R,resistance*A,area)/L,length
5-H,heat=I2Rt
6-P,power=VI=I2r=V2/r
Some more important formulas-
1-F,force=Q,charge*E,electric field intensity
2-V=(K,constant of proportionality of columb's law*Q)/R,distance or radius
3-E=(KQ)/R2
4-F=KQ1Q2/R2
{{Columb's law}}
Note:- K=9*109 N/m
