Question
At high frequency in a capacitive circuit, the current will be:
Solution 1
In a capacitive circuit, the current is directly proportional to the frequency. This is because the capacitive reactance (Xc), which is the opposition that a capacitor offers to alternating current, is inversely proportional to the frequency. The formula for capacitive reactance is Xc = 1/(2πfC), where f is the frequency and C is the capacitance.
So, as the frequency (f) increases, the capacitive reactance (Xc) decreases. This means that the opposition to the current decreases, allowing more current to flow through the circuit.
Therefore, at high frequency in a capacitive circuit, the current will be high.
