The total radiated power is = ( + ()), where = (the velocity of the particle divided by the speed of light), = is the Lorentz factor, signifies a time derivative of , and q is the charge of the particle. Gear teeth are designed so that the number of teeth on a gear is proportional to the radius of its pitch circle, and so that the pitch circles of meshing gears roll on each other without slipping. R) to produce alternative expressions for the amount of power that is dissipated: In alternating current circuits, energy storage elements such as inductance and capacitance may result in periodic reversals of the direction of energy flow. His basic method is still used today: electric current is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet. The device trades off input forces against movement to obtain a desired amplification in the output force. She has an experience of over ten years in writing instructional learning content. Note that th could be 100% only if the waste heat QC is zero. where the input and output forces are determined experimentally.
