I want all the formulas used in chapter electricity

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=I

^{2}Rt

6-P,power=VI=I

^{2}r=V

^{2}/r

Some more important formulas-

1-F,force=Q,charge

*E,electric field intensity*

2-V=(K,constant of proportionality of columb’s lawQ) / R,distance or radius

2-V=(K,constant of proportionality of columb’s law

3-E=(KQ)/R

^{2}

4-F=KQ

_{1}Q

_{1}/R

^{2}

{{Columb’s law}}

Note:- K=9*109 N/m
