AC Voltage applied to a Resistor

The phrase “alternating voltage” refers to a condition in which the direction of the voltage alternates every half cycle. The term alternating current refers to the current that flows through a circuit at any given time. The sine function governs alternating current (AC), which changes its polarity with time. Alternating current is used to power most electrical devices (AC).

AC is a kind of current that may be reversed. When current flows in the opposite direction, it’s known as resistance. Thus, we will see whether a resistor is capable of resisting the flow of AC current. This resistance will be quantified and compared to the resistance in a DC circuit to see whether they are related. 

Electrical resistance is described as a substance that obstructs the flow of electricity. The letter R often denotes it and the Ohm is its SI unit. Ohm’s Law outlines the relationship between resistance and current in direct current voltage. In this article, we’ll learn about AC voltage applied to a resistor, how to use Ohm’s Law when the voltage is delivered in the form of an alternating current.

AC voltage applied to a resistor

Electrical distribution companies had established alternating current as of the industry-standard by now. In India, domestic and industrial electricity is provided using alternating current at a frequency of 50 hertz. In actuality, the majority of our electronics are only resistances. The voltage dips are handled differently since the voltage is alternating at this time, despite the fact that these resistances cause some voltage loss. It is necessary to analyse the resistance’s behaviour when an alternating current voltage is applied to it.

In the case of alternating current, the average or mean value is calculated as the sum of the total current flowing in one complete cycle during a specific time divided by the time required to complete one cycle.

In other words, the average alternating current value is the average of all alternating current values between the source and the peak value.

The root means square (RMS) value is defined in this definition as the total amount of direct current flowing through a given resistance in a given period that produces the same amount of heat as an alternating current flowing through the same resistance during that period. 

Conclusion

Alternating voltage occurs when the voltage direction changes every half cycle. Alternating current is the technical term for the kind of current that is flowing through the circuit at the moment. The alternating current (AC) follows the sine function which changes its polarity about time. AC voltage powers the vast majority of modern electronics.

Resistance is a material that generates blockages in the passage of electric current. It is commonly symbolised by R and its SI unit is Ohm. In DC voltage, the resistance and current are linked to each other using Ohm’s Law. 

Power distribution businesses almost always use alternating currents. Power is supplied to homes and businesses in India using 50 Hz Alternating Current. Quite a few of our modern electronics are nothing more than a collection of impedances. The voltage dips caused by these resistances are handled differently since the voltage is alternating. When an AC voltage is applied to a resistor, it is essential to analyse its behaviour.
