Question 1

A capacitor is charged by connecting it in series with a resistor to a DC source. The greatest change in voltage across the capacitor will occur during:

◦

the first time-constant period.

◦

the second time-constant period.

◦

the fourth time-constant period.

◦

the fifth time-constant period.

Question 2

A lamp connected in series with a capacitor and an AC voltage source will light up. This is because:

◦

the dielectric is shorted out automatically when alternating current is applied.

◦

the peak AC voltage, being higher than the equivalent DC voltage, can temporarily break down the dielectric.

◦

the lamp is also acting as a capacitor when connected in series with an actual capacitor.

◦

the capacitor is being alternately charged and discharged, resulting in a continuous flow of current through the lamp.
