A battery is limited in the amount of current that it can supply to a load. When disconnected and fully charged, the voltage across the battery terminals is measured to be 13.8 V. When connected to a load that dissipates 18 W of power, the terminal voltage of the battery decreases to 12 V.a. What would be the terminal voltage of the battery when connected to a 12 ohm load?b. At what load resistance is maximum power delivered to the load?c. How is this load resistance for maximum power transfer related to the output resistance (Thévenin equivalent resistance)?
A small magnetic needle, which is free to turn slowly in a horizontal plane, is placed at the center of the coil in question (6). Show that it will set at an angle \(\phi\) to B where \(cot(\phi) = 4R/(\pi n^2 \mu_{o}\omega a)\)
Along the way to the page, they pass into a region between two deflecting plates that are 1.6 cm long. There is a 1,500,000 N/C electric field between the deflecting plates. You measure the distance from the edge of the plates to the paper and fin..
Design a circuit using JK flip-flops that takes in a binary stream B0B1B2B3 and outputs 1 at a time t if the stream recieved thusfar (i.e. BoB1..Bt-1Bt), when read as an unsigned binary number, is divisible by 3.
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
A charged particle (charge q, mass m) is moving under the influence of a magnetic field B = B0 az. If the velocity vector of the particle is v = v a ax +- vy ay + vx az Show that the acceleration of this particle lies in the x-y plane.
F = B'D' + A'B'C + ABC + CD' Draw a circuit for this function using only AND , OR, and NOT gates. The function calls for two 3-input AND gates and one 4-input OR gate. All you have available, however, are 2-input AND and OR gates
For each of the following waveforms, determine its period, frequncy, and effective value a) 5 V b) 2sin80t-7cos20t+5 V c) 5cos50t+3sin50t V d) 8cos^290t mA
Assume the coil around the toroid is one single coil and extends all the way around. A toroid is like a donut with a circular cross section. The following characteristics are given: Toroid material = sheet steel, N = 250 turns Inner Radius
A wire is bent in the form of a half loop of radius a=10mm and charged with a line charge density pL=10^-9 C/m. Calculate the field intensity at the center of the loop.
Random variable X is Gaussian with zero mean and variance of 1. Y is defined as Y=X^5. How do I find the probability density function, mean and variance of Y
a piston cylinder device initially contains steam at 3.5 MPa, superheated by 5 C. steam loses heat to the surrounding and the piston moves down hitting a set of stops at which point the cylinder contains saturated liquid water.
Explanation to "Electric circuits" question, The voltage across a load is v(t) = 260 sin (377t + 10 °) and the current through the load is i = 100 sin (377t + 10°). What is the RMS power?
