A circuit element hiden inside a paper bag draws a current that varies with time t (in seconds) according to the current function i(t) = 0.032 sin(2350·t) Amps, while the voltage drop across this element is given by the function v(t) = 8.27 cos(2350·t) Volts. Determine if the hidden element is an inductor or a capacitor, and what is its value?
If the circuit element could be either a capacitor or an inductor, state both possible values below (giving the capacitance value first, and providing correct units for each answer).If the circuit element must be a capacitor (or must be an inductor), enter that single possible value (with correct units) in both boxes.

A dc machine is rated 5 hp with V_f = 240 V, V_a = 240 V, r_a = 0.63 ohms, and L_AF = 1.8 H. At rated condtions w_r = 127.7 rads/s and the total resistance of the field circuit is 240 ohms. a) Calculate the rated armature current.
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any basic circuit element. State the values of all circuit elements (in ohms, farads, etc).
Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz,
A series type Ohmmeter uses a 50 ohm, 1mA PMMC the internal battery voltage is 3V the desired scale marking for half scale deflection is 2000 ohm. Calculate:- - Value of R1 & R2
A rifle fires a 1.20 x 10-2-kg pellet straight upward, because the pellet rests on a compressed spring that is released when the trigger is pulled. The spring has a negligible mass and is compressed by 6.74 x 10-2 m from its unstrained length.
Write the VHDL PROCESS statements for a D flip-flop with asynchronous active-LOW clear, synchronous active-LOW preset, and responsive to a falling edge clock. Use D for the input, Q and for the output, PRE for the preset, CLR for the clear, and CL..
