## FAQs on Difference Between Resistance and Reactance: A Holistic Research

1. What is resistance and reactance?

Resistance is the challenge that the voltage encounters when directing a current through a conductor. The applied voltage to the conductor's ends must be high in order for it to pass a big current. That is, in accordance with Ohm's rule, the applied voltage (V) must be inversely proportional to the current (I) flowing through the conductor, with resistance (R) serving as the proportionality constant. On the other hand, reactance is opposition to a current change. Inductors and capacitors experience reactance when the current is altered. As a result, the frequency of the alternating current passing through an inductor or capacitor has an impact on reactance. Ohm is its unit.

2. Using formula, explain capacitive and inductive reactance?

Capacitive reactance is a measurement of the capacitor's resistance to alternating current. Capacitive reactance is measured in Ohms.

$X_{c} = 1/\omega C$

Inductive reactance, which resembles the resistance to direct current (DC) in a resistance, is the characteristic of an inductive coil that opposes the change in alternating current (AC) through it.

$X_{l} = \omega L=2\pi f L$

3. What is the phase difference between potential difference and current in a circuit comprising only (i) resistor, (ii) capacitor and (iii) inductor coil?

For a resistor, resistance produced has no effect on phase difference between potential difference and current i.e., phase difference is zero. For capacitors which produce capacitive reactance, potential difference leads current by 900 in phase and for an inductor coil which produces inductive reactance, potential difference lags current by 900 in phase.
