Question

i want all formula used in electricity chapter

Answer 1

I =q/t

V=W/Q

1V=1j/C

R=V/A

Rs=R1+R2+R3+.......

Rp=1/R1+1/R2+1/R3+......

H=I2Rt, H= VIT

P=V2/R or P = VI or P =I2R

R =pl/a(where p is a constant)

Hopes it helps

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,cureent*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*Q)/R,distance or radius

3-E=(KQ)/R2

4-F=KQ1Q2/R2

{{Columb's law}}

Note:- K=9*109 N/m
