Find the electric field of a long line charge at a radial distance where the potential is 12V higher than at a radial distance \(r_{1}=1m\) where the magnitude of the electric field is 5V/m .
Consider the problem of using a low-voltage system to power a small cabin. Suppose a 12-V system powers a pair of 100-W lightbulbs (wired in parallel). a. What would be the (filament) resistance of a bulb designed to use 100 W when it receives 12 V
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
A WLAN uses the 1-Mbps IEEE 802.11 infrared standard and the 16-PPM modulation scheme. Compute the period of transmission (time between bits).
determine the efficiency of a high frequency induction furnace which takes 10 minutes to melt 1.815 kg of aluminium the input of the furnace being 5 KW and the initial temperature 15 deg.
Describe the phenomenon of aliasing caused by under sampling. How can aliasing be mitigated What are the advantages of digital communication over analog What is quantization noise How can you reduce it
design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.
It operates at a power factor of 0.85 (lagging) at its rated conditions. Calculate the per-phase current that has to be carried by the cables to the power electronics converter and the step-up transformer located at the base of the tower.
Write the logic equation for Y in terms of A,B,C that solves this problem, and draw the gate-level diagram.
For each of the following systems with input x(t) and output y(t), state whether or not the system is (i) Linear and (ii) Time Invariant. Note that x(t) could be any complex valued signal. (a) y(t) = a^2 x(t), where a is a complex number.
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
The following 4 differential equations describe mass spring systems. Identify each system as either undamped, overdamped, underdamped, or critically damped (Justify your answer). Determine the angular frequency and period for the undamped
If you have 16 kibibytes of memory plus a few (less than 10) memory mapped devices (assume that each device uses 16 bytes of address space), what should the address size be
