Which of the following factors will NOT affect the selection of a resistor?
Resistance is a property that is independent of frequency in direct current circuits. This means that the frequency of the current flowing through a resistor does not influence the value of its resistance. Therefore, when selecting a resistor, the frequency range is not a relevant consideration.
What is the unit of magnetizing force?
Power loss and voltage drop respectively, in the 2Ω resistor is
