An advantage of the universal motor is that AC supplies may be used on motors which have some characteristics more common in DC motors, specifically high starting torque and very compact design if high running speeds are used. The negative aspect is the maintenance and short life problems caused by the commutator. Such motors are used in devices such as food mixers and power tools which are used only intermittently, and often have high starting-torque demands. Multiple taps on the field coil provide (imprecise) stepped speed control. Household blenders that advertise many speeds frequently combine a field coil with several taps and a diode that can be inserted in series with the motor (causing the motor to run on half-wave rectified AC). Universal motors also lend themselves to electronic speed control and, as such, are an ideal choice for devices like domestic washing machines. The motor can be used to agitate the drum (both forwards and in reverse) by switching the field winding with respect to the armature.

Switching the field winding in washing machines causes the drum to agitate how?
Answer: forwards and in reverse

The economist F. A. Hayek analyzed how the Rule of Law might be beneficial to the free market. Hayek proposed that under the Rule of Law individuals would be able to make wise investments and future plans with some confidence in a successful return on investment when he stated: "under the Rule of Law the government is prevented from stultifying individual efforts by ad hoc action. Within the known rules of the game the individual is free to pursue his personal ends and desires, certain that the powers of government will not be used deliberately to frustrate his efforts."

According to Hayek, limited governemnt power through the rule of law does not do what to people?
Answer: frustrate his efforts
