If we double the resistance in a circuit but keep the current in it constant, the power dissipated by that circuit will

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
