battery have a lifetime of 10 years, and is rated at 20 Ah (Ampere-hour) at 3.6V.
Find the average power that the node can consume. Assume 100% battery and power delivery efficiency.
Considering that the only parameters known are the input line-to-line voltage of 415V rms (f=50Hz), the firing angle (a= degrees) and the overlap angle (b=15degrees), calculate the Power Factor as seen from the input AC
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
1.Name and characterize the main source working regimes and write down working regime conditions. 2.Write down the electrical source efficiency factor expression using the parameters of the source and consumer.
A synchronous motor exited by 5 kV source has a synchronous reactance of 5 ohm .The motor is running without any mechanical load(the output real power is zero). Ignore all losses and calculate thr equavelent field voltage Ef that delivers 3 M VAr ..
design a 2 bit up/down counter using 2 d flip flops and gates such that a direction bit set to 0 causes a count up and the same "direction bit" set to 1 causes a count down. show state diagram, state table and circuit
a) what is the frequency f, of the ac circuit signal b) what is the period, T, of the ac circuit signal what is the angular velocity/frequency (omega), of the ac signal if v(t) = 24 cos (2pie 500t).
A single-phase 50-KVA, 2400/240-volt, 60-Hz distribution transformer has a 1-ohm equivalent leakage reactance and a 5000-ohm magnetizing reactance referred to the high-voltage side. If rated voltage is applied to the high-voltage winding
What is bit rate of the transmission on the twisted pair? If the digital outputs of three identical video cameras are combined onto a single cable using time division multiplexing, what is the bit rate on the cable?
he potential field V = 2x^2yz-y^3x exist in a dielectric medium having ε=2ε0 . A) does v satify laplace's equation B) Calculate the total charge within the unit cube 0
With V=100V, the instantaneous power into a network N has a maximum value 1500 W and a minimum value ?247 W. (1) Find a possible series RL circuit equivalent to N. (2) Find S=P+jQ into N.
If an object is located at 0.5 times the focal length of a thin lens, calculate the location and lateral magnification of the image. Assume that both sides of the lens are filled with air, that the index of refraction of the lens is n=1.5
a) Find and plot the straight-line approximations to the amplitude and phase response bode plots b) sketch the approximate amplitude-response bode plot od this system using the straight-line approximation and approximate amplitude values at the br..
