Question - A bridge rectifier is driven by a transformer of turns ratio n1 : n2 = 12 : 1. IF the primary of the transformer is connected to the 220V, 50Hz, 1φ power mains, evaluate the following for the rectifier:
(i) the dc load voltage
(ii) the PIV of each diode
(iii) the dc load current
Assume the diodes to be ideal.
Using data from Fig. 10-9a, calculate the power dissipated in the sample per unit volume when it is biased just below threshold if rc0 is chosen from the calculation of part (a). In general, does operation at a higher frequency result in greater p..
Derive an expression for the ratio of the proportionality constants and plot the distribution of the m = 0 TE mode for a slab waveguide with parameters
A mote draws an average of 200mA when "awake", 0.1mA when "sleeping", and 400mA (total) when "transmitting". Transmitting data takes 2ms, and sensor acquisition takes 1ms. If the maximum size battery available is 5000mAh
noncausal, linear, and time-invariant. Determine the impulse response for the system and verify that an LTI system defined by the impulse response you determined satisfies the difference equation.
What would be the time constant in an RC circuit when R = 200 kn and C = 10 f.lF? If the inductance is 4 henrys, what is the value of circuit resistance?
