Alternating Current Circuit Consisting Elements Current Increases Increasing Frequency

In an alternating current circuit consisting of elements in series, the current increases on increasing the … and a capacitor (d)…

Answers:

(c, d) This is the similar problem as we discussed above. In this problem, the current increases on increasing the frequency of supply. Hence, the reactance of the circuit must be decreased as increase in frequency. So, one element that must be connected is capacitor. We can also connect a resistor in series.
For a capacitive circuit,
X_C = 1/ωC =1/2πfC
When frequency increases, X_C decreases. Hence current in the circuit increases.
