If, at constant resistance, the voltage applied to a section of the circuit is doubled, then how will the amount of heat released change?
With an increase in voltage 2 times, twice with a constant resistance, the current strength increases (Ohm’s law).
Then, according to the Joule-Lenz law (Q = I ^ 2 * R * t), the amount of heat will increase by 4 times.
since the current strength is directly proportional to the amount of heat
