Answer 2

Electric current and the resistance of electrical wire:

Explanation:

• The ratio of a potential difference across the resistor to the current flowing through it is called it is electrical resistance. It is measured with ohms. It is inverse quantity are electrical conductivity, whose unit is Simons.
• {\displaystyle R={\frac {V}{I}}}{\displaystyle R={\frac {V}{I}}}
• Where
• R is a resistance of the object, measured with ohms, equal to J s/C2
• V is the potential difference across to the object, measured with volts.
• I is a electric current passing through to the object, measured with amperes.
• In many objects, resistance does not depend in a current or potential difference, that is a, their resistance remains constant.
