Answer
The new torque is 0.88 of the original torque.
Work Step by Step
Use equation 20–10 to find the torque produced.
$$\tau=NIABsin\theta$$
The output torque is proportional to the current. If the current I is reduced by $12\%$, the output torque is reduced by $12\%$.
In other words, the new torque is 0.88 of the original torque.
