Find the the voltage and current values, Compute as well as their total voltage and current using Kirchoff's law.

Q4.      The equation relating the current in a circuit with time is i=282.1 sin377t, where the current is measured in amperes and the time in seconds. Find the values of: The r.m.s current  The frequency  The instantenous value of the current when t=2.0ms

Compare alternative and direct currents by comparing their physical properties. (Explain alternans, cycles, periods, frequency terms during this comparison. Also in this comparison, explain the electron flow directions separately in alternating and direct current)

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
