The current distribution on a center-fed short dipole (length l n ë) centered at the coordinate origin and lying along the z-axis can be written aswhere Io defines the peak value of the current at the feed point of the antenna. Show that the magnetic vector potential of the center-fed short dipole is related to the magnetic vector potential of the Hertzian dipole by given equal antenna lengths and assuming the value of Io is equal on the two antennas.
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
Write a function called AnalyzeData. This function is passed a double array along with a parameter that indicates the number of elements in the array. It is also passed a double value.
A series circuit has a resistance of 1 ohm and an inductance of 1 ohm. The voltage across the circuit has an amplitude of 15 volts and a phase shift of 30 degrees. What is the current of the circuit in frequency and time domain
Sketch the phasor diagrams for the following waveforms: v1 = 80sin(pi*t + 35°)(a) What is the phase difference between v1 and v2 (b) Determine which voltage leads and which lags.
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
Consequently, this form of serial data communication is known as asynchronous. Compare and contrast this against synchronous serial data communication, giving an example of a synchronous data communications standard.
When the input x(t) = 5u(t) is applied to a linear second-order circuit the response of the state variable is y(t) = 10e^(-100t)-5e^(-200t) + 5. Design a simple RLC circuit that would produce all of these responses.

What will be the output voltage from the bridge for a change in temperature of 20o C The supply voltage to the bridge is 6.0 V and the temperature coefficient of resistance of the platinum is 0.0039 K-1.
A ring placed along y^2 + Z^2 =4, x= 0 carries a uniform charge of 5 uC/m. a.)find D at P(3,0,0). b.) if two identical point charges Q are placed at (0,-3,0) and (0,3,0) in addition to the ring, find the value of Q such that D = 0 at P.
In the pure resistive circuit the current is not not legging, while the resistor provides opposition to the flow of current. Does Current leggs behind the voltage in pure resistive circuit or not.
