Electronics and Communication Analog Electronics Difficulty: Medium

A step-down chopper, fed from a 120 volt DC source, operates a DC motor whose armature e.m.f. and armature resistance are 100 volt and 0.5 Ω respectively. With the magnitude control ratio 0.6, the quadrant of operation DC motor is Which of the following is a portable device of Intel? To couple a co-axial line to a parallel line wire it is best to use A 100 V, 50 Hz a.c. supply is applied across a series RLC circuit having R = 10 Ω, L = 100 mH and C = 1000 µF The current through the circuit will be The drain of an N-channel MOSFET is shorted to the gate such that V GS = V DS . The threshold voltage (V T ) of MOSFET is 1 volt. If the drain current (I D ) is 1 mA for V GS = 2 V, then for V GS = 3 V, the drain current I D is-
