Question

In an alternating current circuit consisting of elements in series, the current increases on increasing the frequency of supply. Which of the following elements are likely to constitute the circuit?

विकल्प

• Only resistor

• Resistor and an inductor

• Resistor and an capacitor

• Only a capacitor

Answer 1

Resistor and an capacitor and Only a capacitor

Explanation:

Here in question on increasing the frequency (f), the current also increases. But resistance does not depend on frequency. So on increasing frequency X_C decreases to increase current in circuit. Therefore, circuit must have a capacitor; however, it may there may not be a resistor.
