Answer / mohamed ghanem

its an indicator for any material that resist the current to pass through this material. and differ from material to another

Answer / suantak

Resistance is the opposition offered by the element to the
current passing through it when a voltage is applied across
the element.

According to Ohm's law, resistance of a material is the
ratio of voltage across the element to the current passing
through it i.e. to say irrespective of the magnitude of
voltage applied, the resistance of that element will remain
constant.

Mathematically, R = Voltage/Current

Answer / ravi

Resistance is a term that describes the forces that oppose the flow of electron current in a conductor which is measured in units called ohms

Answer / buhari

resistance is oppose the flow of current which is expressed as


V=IR

R=V/I

Answer / ashok mishra
