How do I find the specific heat of an object?

If you are given heat and you have to find specific heat, so you have to use this formula

i² x r x t = m x s x Δt

where

I = current

R = resistance

T = time

M = mass

S = specific heat

Δt = change in temperature

c = Q / (mΔT)

c - specific heat

Q - amount of heat

m - mass

ΔT - change in temperature

this comes from the equation Q=mcΔT
