Question 1 of 10
In an inductive circuit, inductive reactance (XL) is directly proportional to:
XL = 2?fL, where f is frequency and L is inductance.
Question 2 of 10
In an inductive circuit, if the inductance (L) increases, the circuit current:
Increasing inductance increases inductive reactance, which reduces current (I = V/XL).
Question 3 of 10
In an inductive circuit, what happens to the power factor when the inductive reactance increases?
As XL increases, the phase angle between voltage and current increases, decreasing the power factor (cos ?).
Question 4 of 10
In a capacitive circuit, capacitive reactance (XC) is inversely proportional to:
XC = 1/(2?fC), where f is frequency and C is capacitance.
Question 5 of 10
In a capacitive circuit, frequency is ___________ proportional to the current.
I = V/Xc and Xc=1/2?fC therefore I ? f.
Question 6 of 10
In a capacitive circuit, capacitance (C) is ___________ proportional to the capacitive reactance (XC).
Xc = 1/(2?fC), which means Xc ? 1/C.
Question 7 of 10
In a capacitive circuit, what happens to the power factor when the capacitance (C) increases?
Increasing capacitance decreases XC, which reduces the phase angle between voltage and current, thus increasing the power factor.
Question 8 of 10
The unit of inductive reactance is:
Reactance is a form of opposition to current flow and is measured in Ohms.
Question 9 of 10
The unit of capacitive reactance is:
Reactance is a form of opposition to current flow and is measured in Ohms.
Question 10 of 10
