A ring charge has charge density ρl = ksin(φ) .It is placed on the xy-plane, centered at the origin, and has a radius of 2.(i) Find the electric field intensity E at (0, 0, h)(ii) Find the electric potential V at (0, 0, h)
Perform the following addition or subtraction of the given numbers using 8-bit 2's complement representation of the numbers. Parts (a) and (b) are given in decimal, while parts (c)-(e) are given in 8-bit 2's complement.
The voltage across a 1x10^(-6)F capacitor is given by v(t)=100e^(-100t) in which time t is in seconds. 1. find an expression for the current 2. find an expression for the power 3. find an expression for the stored energy
A 1.8-kW electric heater takes 15 min to boil a quantity of water. If this is done once a day and power costs 10 cents/kWh, what is the cost of its operation for 30 days
A Na+ ion moves from inside a cell, where the electric potential is -70 mV , to outside the cell, where the potential is 0 V. What is the change in the ion's electric potential energy as it moves from inside to outside the cell
If we have a transfer function T(s) = |Z(s)|/|P(s)| and we had a pole at s=-500; Then the magnitude would be sqrt(500^2 + w). So how does that not decrease the magnitude of the transfer function at frequencies below 500
Write a main program to call a procedure that converts the Fahrenheit temperature value stored in the location labeled TdegF to its Celsius equivalent. The range of temperatures is 32°F to 212°F. The procedure stores the converted temperature
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
1) Modern technology has produced a small 1.5-volt alkaline battery with a nominal stored energy of 150 joules. For how many days will it power a calulator that draws a 2-mA current 2)The current entering the positive terminal of an element is
Then find the phase relation between the total voltage and current; is it leading or lagging when the frequency is below resonance and above resonance; what is the nature of the circuit in those two regions(capacitive or inductive).
Willy has also noticed that the power supply has a current limit that can be set. When he sets the current limit to 8 amperes, it provides exactly 8 amperes, but it doesn't overheat, so it's not shutting off all the time.
A generator (which may be represented by an emf in series with an inductive reactance) is rated 500MVA, 22kV. Its Y-connected windings have a reactance of 1.1 p.u. Find the ohmic value of the reactance of the windings.
Absorption loss of metal shielding, A plane metal shield offers an absorption loss of 30 dB at a frequency of 10 kHz to normally incident radiated emission.
