By definition, the power is equal to the product of the current high squared by the value of the resistance.
In other words:
P = I ^ 2 * R
where,
I: Current
R: resistance
If we double the resistance in a circuit but keep the current in it constant, then:
P = (I ^ 2) * (2 * R)
P = 2 * (I ^ 2 * R)
The power increases twice.
answer:
The power dissipated by that circuit will increase twice
