Question
15. electrolytic capacitors must be connected into a circuit such that:
a. voltage rating marked is not exceeded.
b. reversal of polarity does not happen.
c. positive lead toward positive charge
d. all of these.
16. the time constant for a capacitor is:
a. directly proportional to the capacitance in the circuit.
b. directly proportional to the resistance in the circuit.
c. the time required to charge to 63% or to discharge to 37%.
d. all of these.
17. if a .05 microfarad and .1 microfarad
capacitor are connected in parallel across the 20 volt Source the total capacitance equals ___________ and each capacitor drops
a. .05 microfarad , 15 volt
b. .15 microfarad, 20 volt
c. .15 microfarad, 10 volt
d. .10 microfarad, 20 volt
Explanation / Answer
15) All of these (d) : Electrolytic capacitors have polarity. If a supply is given above its marked value, then it may get damaged.
16) All of these (d) : time constant = R*C where R is resistance of the circuit
C is Capacitance of the circuit
17) 0.15 microfarad, 20 Volt (b)
since capacitors are in parallel, they will simply get added and supply voltage in the circuit will remain same.
