In the circuit shown below, R1 = 3 k ohm, R2 = 6 k ohm, R3 = 5 kohm, R4 = 8 kohm, R5 = 9 k ohm, R6 = 4 kohm, R7 = 9 k ohm, V1 = 9 v, V2 = 6 v, and IS = 9 mA. Using superposition, find the current i0 shown, in units of mA, approximated to 2 decimal places.
The full-wave rectifier in the figure given below is operating at a frequency of 60 Hz, and the rms value of the transformer output voltage is 18 V. Calculate the minimum value of capacitance required to maintain the ripple voltage to less than 0.25 V if R = 0.5 Ω. (Round the final answer to three decimal places.) The minimum value of the capacitance C required to maintain the ripple voltage is F
