The ratio of output power to input power of an elecrtic device is called…….

A viscous clutch as shown in figure tranmits torque. Radius of each clutch plate is R and separation between the plates is a and is completely filled with liquid of coefficient of viscous mu . If omega_(i) and omega_(0) are angular velocities of plates connected to input and output respectively. If efficiency of transmission is ratio of output power to input power, then efficiency is given by

The ratio of the output force (Load) and the input force (Effort) is called ____ .

For an ideal transformer ratio of output ot the input power is always

An aspect of Input/Output controller of data logic is called.

The ratio of secondary to the primary turns in a transformer is 3:2 . If the power output be P , then the input power neglecting all loses must be equal to
