Answer clearly True or False No Abbreviations please Negativ

Answer clearly: True or False: No Abbreviations please Negative current is in the same direction as the flow of electrons; Inductance stores the energy in the form of associated magnetic field; NPN Transistor is faster than the PNP transistor of same dimensions; Inductive voltage can change instantly; Capacitive Energy can-not change instantly; Diode conducts if Cathode is negative compared to Anode; Bridge Rectifier system should have [1 Diode, 2 Diodes, 4 Diodes, None of these (How many)? VAN voltage of balanced 3 phase system is 480 Volts at Zero degrees. What is the magnitude and phase angle of interface voltage VBC, in the ABC sequence; What is the resonant frequency f in Hz, for 10 Micro Henries in parallel to 10 Micro Farads; R1 = 2k, R2 = 22k, R3 = 6k, R4 = 3k, RL = 5k; C is of proper value. V_0 Power supplies. System has been running for long; at t=0 + V_0 output jumps from -12 volts to +12. When will the diode be on [when V_0 is at +12 volts, when power is turned on, does conditions (which)] why?

Solution

(a) FALSE

By definition, the electric force

F = qE

Electrons have negative charge, and so the force on them is opposite the direction of the electric field. In a conductor, this leads to electron flow in the direction opposite the electric field.

(b) TRUE

(c) TRUE

It has faster mobility of electrons. It is most suitable for negative ground system.

(d) TRUE

(e) TRUE

I = C * dv/dt

(f) TRUE

Diode is forward biased in this case.

(g) 4

(I) f = 1/2LC

f = 10^5/2 Hz
