Answer 1

Explanation:

electric current :

the time rate of flow of electric charge ,in the direction that is positive moving charge would take and have magnitude equal to the quantity of charge per unit time measured in amperes .

Ohm's law :

the all law that for any circuit the electric current is directly proportional to the voltage and inversely proportional to resistance .

convex lens :

a lens having at least one surface that curves like the exterior of the sphere .

concave lens ;
