The characteristic of a material to resist the flow of current through it, is known as resistance. When any element is subjected to an electrical potential difference or a voltage […]
Resistivity and Laws of Resistance
Resitivity which is also known as Coefficient of Resistance is a property in a substances which causes an opposition to current flow within that substance. This can be easily calculated […]
Temperature Coefficient of Resistance
From our earlier discussions we have understood that electrical resistance of all elements changes in response to the variations in its temperature. Temperature coefficient of resistance is defined as the […]
