1. Here's a pencil and paper. Tell me how a bridge rectifier with a capacitor-input filter works. In your explanation, I expect to see a schematic diagram and waveforms at different points in the circuit.
2. Suppose there's a bridge rectifier with a capacitor-input filter on my lab bench. It's not working. Tell me how you would troubleshoot it. Indicate the kind of instruments you would use and how you would isolate common troubles.
Calculate the critical clearing angle and plot the swing curve for the machine - What is the power angle at the end of the 10 cycles?
a) Assume B1 = ax2 - ay10(mT), find B2 and the angle that B2 makes with the interface. b) Assume B2 = ax10 +ay2(mT), find B1 and the angle that B1 makes with the normal to the interface.
Apply the IDWT to determine the 2D data.
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
[1] If the speed of a DC machine is doubled and the flux remains constant, the generated e.m.f. (a) remains the same (b) is doubled
Suppose we have a voltage source v(t) = Vdc + Vm cos( ωt) connected to the input terminals of an amplifier. The load is a nonlinear device such as an LED. What output impedance is needed for the amplifier if we need the current through the load to ..
Describe the components of the Saudi Arabian electronic health system
A silicon diode with a breakdown voltage of 2000V that is conducting a forward current of 2000A is turned off with a constant diR/dt=250 A/s. Roughly estimate the time required for the diode to turn off.
How to Program PIC18 Microcontroller in C. ?? (with expalanation and examples )
Estimate the minimum window length L that will meet these requirements.
You will need to go to a manufacturer's website (ex: Motorola) to get the datasheets. The specifications for the different kinds of diodes vary. Copy all of the specifications for each diode as well as all of the specification definitions.
The rate of production of ATP in the cell is about 10 million molecules per second. The steady-state number of ATP molecules in the human body is about 0.1 mol. The number of cells of a human body is approximately 1014.
