Question: In an RLC circuit, if the resistance is increased while keeping the inductance and capacitance constant, what happens to the bandwidth?

Options:

Correct Answer: Decreases

Solution:

The bandwidth (Δf) of an RLC circuit is inversely proportional to the resistance (R). Increasing R decreases the bandwidth.

In an RLC circuit, if the resistance is increased while keeping the inductance and capacitance constant, what happens to the bandwidth?

Step 1: Understand what an RLC circuit is. It consists of a resistor (R), inductor (L), and capacitor (C).
Step 2: Know that bandwidth (Δf) is the range of frequencies over which the circuit can operate effectively.
Step 3: Remember that in an RLC circuit, bandwidth is affected by the resistance (R).
Step 4: Learn that bandwidth is inversely proportional to resistance. This means that as resistance increases, bandwidth decreases.
Step 5: Conclude that if you increase the resistance while keeping inductance and capacitance constant, the bandwidth will decrease.
