Resistance is the measure of how much a material or component opposes the flow of electric current. In electrical terms, resistance is defined as the ratio of voltage to current in a circuit, measured in ohms.
The base units of the ohm are the volt and the ampere. In the context of electrical resistance, the ohm is defined as the resistance that limits the flow of electric current when one volt is applied across it and one ampere of current flows through it.
No, they are not the same. Electrical resistance is a measure of how much a material opposes the flow of electric current, while resistivity is a property of the material itself that determines its resistance. Resistivity is an intrinsic property of the material, while resistance depends on the dimensions and shape of the material.
ESR stands for Equivalent Series Resistance. It is a measure of the internal resistance of a capacitor. Lower ESR values indicate better performance in terms of energy efficiency and stability in electrical circuits.
Electric current is considered a base quantity because it is an independent physical quantity that cannot be defined in terms of other fundamental quantities. It is a fundamental building block in physics and is used to define other electrical quantities such as voltage and resistance.
The relationship between resistance and current in an electrical circuit is described by Ohm's Law, which states that the current flowing through a circuit is directly proportional to the voltage applied and inversely proportional to the resistance in the circuit. In simpler terms, as resistance increases, the current flowing through the circuit decreases, and vice versa.

The relationship between volts and amps in an electrical circuit is defined by Ohm's Law, which states that voltage (V) is equal to the current (I) multiplied by the resistance (R) in the circuit. In other words, volts per amp is a measure of resistance in the circuit.
electrical resistance was discovered by Georg Ohm in the late 1820's.
The units of resistance in an electrical circuit are measured in ohms ().
