Consider a uniformly charged sphere of radius R1 with a spherical hole of radius R2 displaced a distance x0 from the center. Let ρ be the charge density.a) What is E on the x axis as a function of x?b) What is E on the y axis as a function of y?(Hint: The superposition of two spheres of radii R1 and R2 and of equal and opposite charge densities has the same solution).
With |V| = 100 V, the instantaneous power p(t) into a network N has a maximum value 1707 W and a minimum value of -293 W. Find a possible series RL circuit equivalent to N.
Create a function that transmits one byte to an HD44780 LCD controller using the following sequence. Allow one microsecond between each instruction. To clock in a byte: Set the E line low.
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
