Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of Us fanner value. What change will occur in the current through it?
Ohm's Law: It defines that the current through a conductor between two points is directly proportional to the voltage across the two points. The formula of Ohm's Law: V=IR V=potential difference I=current R=resistance So I = V/R Now, on the basis of the question, the potential difference is decreased to half V1= V/2 . According to question resistance remains constant. Then the new current is: I1= V/2/R I1=I/2 Hence, the current is reduced to half through it.
