If an uncharged capacitor a resistor a switch and a 12 V bat

If an uncharged capacitor, a resistor, a switch and a 12 V battery are connected in series, what is the voltage across the capacitor at the instant the switch is closed? A) 12 V B) 24 V C) 6 V D) 0 V Electrolytic capacitors must be connected into a circuit such that: positive lead to positive voltage; negative lead to negative voltage. reversal of polarity does not happen. voltage rating marked is not exceeded. d. all of these. If the operating frequency decreases in Figure 12-1, the inductance A) remains the same B) decreases C) increases D) decreases to zero Which of the following is typically most important of the three types of power in terms of work being done? A) apparent B) inductive C) true D) reactive Thevenizing a circuit creates an equivalent series circuit. Maximum power is achieved when the load resistance is approximately two times the source resistance. Magnetic flux is another name of a magnetic field d. Flux lines are concentrated at the center of a magnet. e. The higher a sine wave\'s frequency, the shorter its period. f. One complete sine wave contains 360 degree. g. A capacitor can fully charge in one times constant. h. A capacitor blocks dc and passes ac. i. A leaky capacitor can be equated as a capacitor with a resistor being placed in series with it. j. The voltage leads the current in an inductive circuit.

Solution

c) FALSE :magnetic flux is not another name for magnetic field

Magnetic flux is a measurement of the total magnetic field which passes through a given area

H) TRUE

DC has zero frequency, so reactance is infinity. This is the reason DC is blocked. While AC has some frequence,

due to which capacitor lets it flow

F) FALSE

one complete sine wave contains 180 degrees

E)TRUE

T=1/F so higher the frequency shorter the time period

D) TRUE

magnetic field lines are concentrated more at centre of magnet
