Answer:
pls mark me as the brainliest
Explanation:
Look carefully. Those equations are not the same. The second one is also incorrect: P=V^2/R The power formula, or H=T*V^2/R Heat formula.
The first one: H=I^2*R*T — H is the heat in joules with I in Amps, R in ohms and T in seconds.
V=I*R [Ohm’s Law]
P=I*V [Power formula]
H=P*T [Heat, power relationship]
Substitute correctly and you’ll see the error.
