I = V/R.
Current is inversely proportional to the resistance that's why it increases when resistance decreases as it is connected in series in the circuit.
Since we don't know the exact value of resistance we can't say whether it increases 1/3rd or 1/4th or etc but it is going increase.

As the 3 resistances are connected in series the total resistance is the sum of the 3 resistances. As one of the resistance is removed the total resistance will be lesser than this. Since the current is i=v/r the current will be greater than the original current.

By the ohms low wn khow that:
V=IR.
Then,
Current (I) =V/R.
Resistance (R) =V/I.
By the above explanation we can easily see that the resistance is inversely proportional to the current. So when the no.of resistance decrease the current will increase.
V=IR.
Then,
Current (I) =V/R.
Resistance (R) =V/I.
By the above explanation we can easily see that the resistance is inversely proportional to the current. So when the no.of resistance decrease the current will increase.

Since Resistors are connected in series, say same resistance, same current flows through them, ie I/3, I/3 and I/3. When one resistance is removed, the circuit has to compensate that with an increase in current. Therefore, the current increases by I/3.

That is why I am amazed.
In series circuit current is always same. But according to Ohm Law, it increases and decreases proportionally to the resistors.
As no option for steady current is given. So, the answer A is the most right one.

In a series circuit, the current remains same through each and every resistance. Only the voltage drop changes across resistance depending on its value.
So, I think the options are wrong.

Hello friends,
In series circuit current remains the same. Even you have high resistance or low resistance because current is constant in series connection.

I = V/R.
Since voltage is constant and I is inversely proportional to resistance R. Henceforth the current will increase when resistance is least.

Actually, in question they will not be mentioned whether the circuit is in series are parallel so acc to ohms law as they are decreases I increase.

In series resistor total current is same as series resistors. When in this case, one resistor remove then total current is change by Ohms law.
