I want all the formulas used in chapter electricity
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,currentR,resistance
4-Resisitivity=(R,resistanceA,area)/L,length
5-H,heat=I2Rt
6-P,power=VI=I2r=V2/r
Some more important formulas-
1-F,force=Q,chargeE,electric field intensity
2-V=(K,constant of proportionality of columb’s lawQ) / R,distance or radius
3-E=(KQ)/R2
4-F=KQ1Q1/R2
{{Columb’s law}}
Note:- K=9*109 N/m
