Question

Write all fourmulas of electricity chapter....

Answer 1

1- I,current=Q,charge/T,time

2- V,potential difference=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 coloumb's law*Q)/R,distance or radius

3-E=(KQ)/R2

4-F=KQ1Q2/R2

{{Columb's law}}

Note:- K=9*109 N/m

Answer 2

I = Q/t
I = V/R
P=W/t
P=I2R
P=V×I
P=V2/R
