If the current in the circuit is doubled, and the time it takes for the current to flow through the conductor is reduced by 4, then the amount of heat released by the conductor …

According to the Joule-Lenz law, the amount of heat that will be released on the conductor:
Q = (I ^ 2) * R * t, where I is the current strength, R is the resistance of the conductor, t is the time the current passes through the conductor.
The amount of heat released by the conductor after increasing the current strength by 2 times and reducing the flow of current by 4 times:
Q = ((2I) ^ 2) * R * (t / 4) = 4 (I ^ 2) * R * (t / 4) = (I ^ 2) * R * t.
Since the formula has taken on its original form, the amount of heat released by the conductor will not change.
Answer: will not change.
