Question

$please tell me all formulas involved in electricity chapter.$

Answer 1

I=v/r

P=v square/r

I=p/v

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
