If you quadruple the voltage across a resistor while at the same time cutting its resistance to one-fifth its original value, what happens to the current in the resistor?

Respuesta :

The current in the resistor  increases by 15 times

if current doubles it increases by five times

as per ohms law V = iR if V is tripled and R is reduced to 1/5th i = v/R

i' = 3V/R/5 = 15 i it increases by 15 times

According to Ohm's law, the voltage across two places is precisely proportional to the current flowing through a conductor between them. Introducing the proportionality constant, the resistance
