A method and apparatus for protecting a circuit are provided. The method and apparatus may measure a physical quantity of a motor by an external physical stimulus, may calculate the related counter electromotive voltage generated by the motor, based on the physical quantity, may compare the counter electromotive voltage to an output voltage, and may open a circuit connected to the motor to be open when the counter electromotive voltage is greater than the output voltage. The protection method and apparatus is applied to a walking assistance apparatus. |
