A commutator motor with its armature supplied from variable voltage source. As the voltage is varied from 0 to 600V,the drive speed varies from 0 to 1600rpm, the field flux isconstant, all losses-ignored.a) determine armature current if load torque is constant at420 N . mb)a load is driven in the speed range of 1600 to 4000rpms. the armature V is constant at 600V. Determine torque available at maxspeed if the armature current of part (a) is not to b eexceeded.
As the ball rises, it gradually loses kinetic energy as its potential energy increases. At the top of its flight, when its vertical speed goes to zero, all of the kinetic energy has been converted into potential energy.
Write a function called Balloon that will accept a single variable named S. The function should replace S with the square of S and repeat this process until S is either greater than 10^15 or less than 10^-15.
G=X'Y'Z'+XYZ+XY'Z+X'YZ' A) Simplify this equation using boolean algebra (theorems),show each step please. B) Simplify this equation using a Karnaugh map.
1) Briefly explain what happens when the VSYNC goes from '1' to '0' for negative sync polarization2) Briefly explain what happens when the HSYNC goes from '1' to '0' for negative sync polarization
A) each charge is qual to q. Find the points in space at which the field intensity is zero. B) two charges are qual to q the third to 2q. show that the electric field intensity is zero only at infinity.
Two watt-meters connected to read the total power drawn by a balanced three-phase load. If the two readings are 1000 W and -1000 W, what is the total power drawn by the load
A single, common-anode, 7-segment LED is connected to the Arduino Connector J1 through current-limiting resistors. The diagram in Figure 1 shows the mapping of the pins of the connector to the pins of the 7-segment.
On a spacecraft two engines fire for a time of 541 s. One gives the craft an acceleration in the x direction of ax = 4.90 m/s2, while the other produces an acceleration in the y direction of ay = 7.60 m/s2.
Suppose a coaxial capacitor with inner radius 1.0 cm, outer radius2.0 cm and length 1.0m is constructed with two differentdielectrics. When oriented along the z-axis, εr for0o
Detailed Explanation to Op-Amp, A certain op-amp has an open-loop voltage gain of 100,000 and a common mode gain of 0.2. Determine the CMRR in dB.
1. Choose a sampling rate of Fs = 40 kHz. 2. Create a vector t of 32768 time-sample points spaced according to this Fs, starting at 0 seconds. 3. Compute a vector x of 32768 samples of a 5400 Hz sinusoid with amplitude of square root of 2.
Design an AC source system that can be used to power 120 Vrms, 240 Vrms, and 208 Vrms single phase devices depending upon the particular connection terminals. The system should have no individual sources with voltages larger than 120 Vrms.
