All formula of physics class X CBSE

Answer 1

e=pt
p=vi
v=ir
v=w/q
h=i2rt
r=v/i
m=-v/u and + for mirror
1/f=1/v+1/u and-for lens
1/p=d
study
right hand and left hand rule
series r= r1+r2+r3
parallel 1/r1+1/r2+1/r3 =1/r

Answer 2

r(series)= sum of all resistors

1/r(parallel)=1/r1 + 1/r2 + 1/r3

mirror formula :
1/F = 1/v + 1/u

lens formula:
1/F = 1/v - 1/u

magnification :
height of image/height of obj

p=vi 

v=ir

v=w/q

h=i^2rt

v=wavelenth*frequency  

e=pt
