Does a resistor reduce current and voltage?

Time:2019-07-01 14:12:00 Click:

Absolutely! In fact, resistor is like a current limiter, which limits the amount of current flowing through a device.


Suppose you have to apply a certain current of 5 amperes to a device input and you have 10 amperes source so what would you do ? As far as I am concerned, it's totally available to add a resistor in series to limit the current.


In other words, this resistance will create a voltage drop (reduces voltage in that area or drops potential) and reduce the current passing through the circuit finally.


Working principle:

1.Current is defined as amount of charge flowing in a given time so that it virtually limits the flow of electrons;

2.In the process of limiting the flow of current and reducing voltage, a resistor absorbs electrical energy, which is released in the form of heat.
