Using 2nd approximation for the circuit shown, assuming that the diode used is a silicon diode, determine the currents ID1, ID2 and current through R2. Finalize answers as follows: ID1= ID2= Ir2= R2 D1 3.3 kQ ВАT1 D2 20 V R1 5.6 kQ

An iron core 0.4 m long and 5 cm2is wound with 300 turns. When a current of 0.5A flows in the coil, how much is the inductance of the coil. Assume the core has a permeability of 2500.

You have developed an idea for using a poly Si surface‐ micromachined cantilever. Initially, you designed a process flow for creating this simple structure, and the process flow is detailed in the figure below. ( cross section view and top view)There are several critical errors with this process (things that won’t work or won’t produce the result). Please find the critical errors in this process flow and, where possible, suggest alternate approaches. Do not worry about the accumulation of errors, but rather treat each step assuming that the structure up to that step could be created.This structure is actually quite simple to make. Develop a simpler process flow and associated masks to create the final structure. Be sure to show cross‐sectional and planar views of all key steps in the process.

Two cities A and B are connected by a 200km long train line. A train leaves A for B at 20 km / h at the same time as another train leaves B for A at 5 km / h. In the samemoment a fly leaves from A to B following the train line. The fly flies at 40 km / h until it collides with train B. At that moment it returns instantly and follows the train line until it collides with train A. At that moment it returns instantly and follows the line of the train. train until it collides with train B. The fly continues this process, traveling ever smaller distances until the two trains meet. (It is an ideal problem and the fly does not get squashed by the trains).What is the total distance traveled by the fly?

A load can be considered to be capacitive, resistive or inductive in nature.a) Discuss the differences between these types of loads. Your discussion should include the following: A description of the type of the load and why it is considered to be capacitive, resistive or inductive. How/whether energy is stored. An example where possible, and a comment on how common that type of load is. How the load will respond to a sudden removal of the driving voltage.

Two coils are placed close to each other as shown in the figure. The coil on the left is connected to a battery and a switch, and the coil on the right is connected to a resistor.What is the direction of the current in the resistori. an instant after closing the switch?ii. after the switch has been closed for several seconds?iii. an instant after opening the switch?Choose your answers betweento. on the leftb. on the rightc. the current is zero.And clearly explain the reason for your answer.
