If the current in a pure inductor in a radio is 120microA when the voltage amplitude is 0.3v at a frequency of 1.2HZ. Calculate the inductive reactance
The inductive reactance (XL) of an inductor can be calculated using the formula:
XL = V / I
where:
XL = inductive reactance
V = voltage amplitude
I = current
In this case, V = 0.3V and I = 120μA (which is equivalent to 0.00012A). Plugging these values into the formula, we get:
XL = 0.3 / 0.00012
XL = 2500 ohms
Therefore, the inductive reactance of the inductor in the radio is 2500 ohms.
