. A constant inductance of 1 henry and a variable resistance R are connected in series with a constant emf of E volts. If R=- ohms at time t seconds and if the current is initially zero, what value of E will make the 1+t current 24 amperes after 4 seconds?

Explain the significance of Kirchhoff's laws in electrical engineering. Please don't use AI solution

Specify the LM-series linear regulator required to regulate a fixed voltage of -19 V. Please write the numbers only in the answer field: i.e. for LM1234, you would write 1234 in the answer field.

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.

Please answer in typing format please ASAP for the Thanks in advance Please all subpart is compulsory

THE POLARITY MARKINGS ON TWO WINDINGS MUST BE DETERMINED EXPERIMENTALLY. THE DEVICE FOR SUCH DETERMINATION IS SHOWN IN THE FIGURE BELOW. THAT THE TERMINAL CONNECTED TO THE POSITIVE TERMINAL OF THE BATTERY RESERVES THE POLARITY MARKING AS SHOWN IN THE FIGURE. WHEN THE SWITCH IS OPEN, THE DC VOLTMETER UNDERGOES A NEGATIVE DEFLECTION. WHERE ON THE CONNECTED WINDING SHOULD A POLARITY MARKING BE ATTACHED TO THE VOLTMETER? t = 0 R )cc VOLTIMETER VB- CHOOSE AN OPTION BELOW: A. POINT AT THE LOWER END OF THE INDUCTOR B. POINT AT THE TOP END OF THE INDUCTOR C. NONE OF THE OPTIONS D. A DOT AT THE TOP END AND BOTTOM END C E. THERE IS NO COUPLING BETWEEN THE INDUCTORS, SO IT IS NOT NECESSARY TO PLACE A DOT

20 What is countertorque a measure of? PRACTICAL APPLICATIONS ou are working as an electrician in a large steel manufacturing plant, and Y in the of doing preventive maintenance on a large DC you are generator. You have megged both the series and shunt field windings and found that each has over 10 M2 to ground. Your ohmmeter, however, indicates a resistance of 1.5 2 across terminals S, and S,. The ohmmeter indicates a resistance of 225 N between terminals F, and F2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer. process

Please show all work, thank you :)
