Two batteries with emf's of 1.5V and 1.2V and internal resistances of 0.50-ohm and 0.80-ohm, respectively, are connected in parallel with + terminals together.a.) Determine the current they would deliver to an external resistance of 2.0?b.) Would more current be delivered if only one battery were used? If so, which one?
A binary waveform of 53000 bits/sec is converted into an 8192 level waveform that is passed through a channel with a raised cosine-rolloff filter characteristic with r = 0.33. The channel bandwidth is what
we know Ktw=1 Nm(rad/s) and its's rated torque 30Nm for the synchronous frequency 60 H. If this motor is running at 60Hz, its load torque changes from 30 to 10 Nm, what is the new motor speed.
A flashlight battery with a voltage of 1.2 would be considered. During servicing, Ni-Cad batteries are normally overcharged to of the rated amp-hour capacity. What is done in an airplane in flight to mitigate this complication
A radio link has a transmitter with a power of 1 W and an initial noise of 16 mW. The receiver has a sensitivity of 125 mW and can tolerate a SNR of 15 dB. What is the maximum noise power that can be inserted
Alice passes through four traffic lights on her way to work, and each light is equally likely to be green or red, independent of the others. Let X be the number of red lights that Alice encounters. Let A be the event that the first light is red.
Calculate the maximum power that can be sent through an a=2cm , b=1cm air-filled waveguide at 12 GHz such that dielectric breakdown does not occur. Assume that the dielectric strength of air at atmospheric pressure is 3x10^6 [V/m]
For the discrete signals defined as the following: x[0]=4, x[1]=1, x[3]=-1, x[n]=0 for all other integers n. v[0]=1, v[1]=-2, v[2]=3, v[3]=-4, v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n
A single-phase transformer has two 120V windings (primary) and one 240V windings (secondary) such that with the two primary in series properly (dot to no dot) the transformer is a 240:240V transformer. A test is run on one of the primary coils (one..
Analysing harmonic content of ac voltage waveforms, An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental
