law of ohm
the strength of a direct current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit
V=IR
potential difference is directly proportional to the flow of current in a wire and directly proportional to tje resistance of wire V=IR V=potential difference I=current R=resistance of wire
When two fixed point charges are q¹ and q and the distance between them is r, then according to Coulomb's law, the product of two charges and inversely proportional to the square of the distance between them
