A 15 microfarad capacitor is connected to a 220v

Asked by admin @ in Physics viewed by 290 People

A 15.0 uF capacitor is connected to a 220V, 50 Hz source. Find the capacitive reactance and the current (rms

and peak) in the circuit. If the frequency is doubled, what happens to the capacitive reactance and the current?​

Answered by admin @


Explanation:

using ,

capacitive reactance=1/wc

w=2×3.14×frequecy

c=15×10^( -6)

in this way we can have value of capacitive reactance

if "f" is doubled then capacitive reactance becomes half

now for current,i=£/capacitive react

if "f" is doubled current too becomes double
