Consider the device like a primitive relay. The armature on the right would be guided and aligned with the core on the left. A return spring would be used to pull the armature back to the right once the coil is de-energized. The springs effect is addressed below. As a relay some contacts are connected to, and move with, the armature. Other contacts are stationary and would make or break contacts as the armature moves. The following characteristic re given: Core and armature material = cast steel, us Fig 1-5(b), pg. 3. N = 500 turns Mean core path through the core and armature = 360mm Each air gap between core and armature = 1.5mm With the given airgap, a flux density B = 0.8T is required to move the armature and actuate the relay. This is required to overcome the spring. Determine: (a) Find the current in the coil. Hint: the air gap is so small, fringing is negligible. (b) What is the permeability of the relay's magnetic circuit, m, assuming (a). (c) Repeat the problem with the air gaps zero. Find the new current necessary to maintain B = 0.8T.
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
Problem Statement: Solve the load flow problem below in Matlab, or similar program, using the Gauss-Seidel Method.
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
