1. Calculate the charge transferred in 25 minutes by a current of 500 mA.
2. A current of 3.6 A transfers a charge of 375 mC. How long would this take?
3. Determine the value of charging current required to transfer a charge of 0.55 mC in atime of 600 s.
A marine biologist is monitoring a dolphin swimming in seawater where the speed of sound is 1520 m/s. When the dolphin is swimming directly away at 5.4 m/s, the marine biologist measures the number of clicks occuring per second to be at a frequenc..
Problems for the basic concepts of Induction motor(IM) taking care of slip and syncronous speed and motor speed and its relationship, A 50 Hz induction motor operates in such a way that the slip is 1.45.
A common energy consumption for a family is about 1000 kW hr / month. How much power would that be on the average. (Hint: Notice that hour and month are both units of time so kW hr per month is really a power unit.
In telecommunication systems, Time-Division Multiplexing and Frequency -Division Multiplexing are used. Give detailed explanations for both systems and give succinct examples for each of them.
For the differential amplifier shown in Fig. 4-8, R1 and R2 are 1% resistors with values of 4.7 k Ω and 270 k Ω, respectively.
The process of stereophonic broadcasting was illustrated in Chapter 3. By comparing the noise power in the l(t)-r(t) channel to the noise power in the l(t)+ r(t) channel, explain why stereophonic broadcasting is more sensitive to noise than nonste..
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
The first stage is a transconductance amplifier with an input resistance of 2k ohms, an output resistance of 100k and a gm=0.002A/V. The second stage is a voltage amplifier with an input resistance of 5k, an output resistance of 18 ohms and a volt..
Determine the entropy of the source. What is the maximum entropy of a source with five outputs?
What is the effective radiated power of a television broadcast station if the output of the transmitter is 1000 W, antenna transmission line loss is 50 W, and the antenna power gain is 3
A sinusoidal voltage source vs = 100cos 105t V, a 500Ω resistor, and an 8 mH inductor are in series. Determine those instants of time, 0≤t
