Question

how many formulas are in the chapter electricity class 10?​

Answer 1

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

Answer 2

Current=charge/time

V=W/Q

V=IR

R=V/I

R=pL/A

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

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

P=VQ/T

P=VI

P=V square/R

P=I square R

1KWh=3.6×10^6J

H=VIt

H=I square Rt
