V=ir
p=i2r
p= v2/r*
r= rho*length/area
heat = p*t
p= i*v
r(series)= r1+r2+r3...
r (parallel)= 1/R= 1/r1+1/r2+1/r3.......

V = potential
R = resistance
I= current
P= power
H = heat
T = time

V= IR

P = VI = I²R = V²/R

H = I²RT

R = ρ﻿﻿

ρ = resitivity
le = length of wire

A = area of cross-section

for series connection
R = R₁ + R₂ ....... n resistors

for parallel connection

R =  ......n resistors
mine was better
where is the breliant option
??
means ?
both the ans are best
