1. The switch of given Figure is closed at t = 0 s. How long is it until current reaches its steady value?
2. An unknown circuit containing dc sources and resistors has an open-circuit voltage of 45 volts. When its output terminals are shorted, the short-circuit current is 0.15 A. A switch, resistor, and inductance are connected in given Figure. Determine the inductor current and voltage 2.5 ms after the switch is closed.
A random sample of 50 mathematics grades out of a total of 200 showed a mean of 75 and a standard deviation of 10. (a) What are the 95% confidence limits for estimates of the mean of the 200 grades
What do they mean by these two statements. For example, are they asking us to keep Voltage or Current constant in either statement and vary the Resistance finding the unknown Voltage or Current or what
determine whether a three bit number , a3,a2,a1 is equal to another number b3,b2,b1 or if it is greater than that number (We do not need an output for less than) a)Show how the 7485 would be connected to accomplish this.
f(t) = t. B. f(t) = Sin wt find F(s). C. f(x) = y" + 2y' +y D. f(x) = y"' +4y" + 6y' + 9y. E. Given a serious electrical LRC circuit with an input source of 3Sin wt find the current i(t) expressed as I(s). Hint: use jwL and 1/jwC and w = 2pief
