Detailed explanation-1: -over a wide range of voltages and currents. Therefore, the resistance and conductance of objects or electronic components made of these materials is constant. This relationship is called Ohm’s law, and materials which obey it are called ohmic materials.

Detailed explanation-2: -If the current is held constant, an increase in voltage will result in an increase in resistance. Alternately, an increase in current while holding the voltage constant will result in a decrease in resistance.

Detailed explanation-3: -Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR.

Detailed explanation-4: -Hence, resistance is constant in a circuit.

Detailed explanation-5: -Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Ohm’s law formula is written as; V ∝ I. Therefore, V = RI where R is a constant called resistance.
