Answer:
When Original resistance= R,
Volatge= V
Then, Current 1=I=V/R (by Ohm's law)
New resistance=R/3
Voltage= V
Then, Current 2= I = V/(R/3)
=V*3/R
=3V/R
Thus, Ratio Current 1/ Current 2= (V/R)/(3V/R)
=V/R*R/3V
=1/3
Hence the ratio = 1:3

When the resistance of a conductor becomes one third of the original then the ratio of the current before and after = 1:3
Explanation:
- According to the ohm's law the current in the circuit is inversely proportional to the resistance of the conductor which is present in the circuit. As a result of this if the resistance becomes one third then the current will be 3 times.
- This occurs only when the potential difference remains constant in the circuit
