We know that if voltage increases, current increases & if resistor increase then current decreases.. then in parallel current ckt as increases total resistance also increases...

In series voltage is constant therefore in the circuit only changes current ane of the fact is that resistance decreases then current also increases as per ohms law.

Take V = IR relation.
In parallel circuit voltage is constant. So IR must be a constant value if one terminal is open means I = 0. So R became infinity.

No. The given answer is wrong. It may increase or decrease resistance value depending on the value of resistance.

If one of the resistors that are connected in series is opened, then total resistance becomes infinite.

What will be answered if more than two resistance is connected in a circuit? Like, r1=2, r2=3, r3=4.

If R1 is in series with parallel connected to R2 and R3, what happens to total current if R2 opens?

If one of the resistors in a parallel circuit, is removed, what happens to the total resistance?

In a parallel circuit, if any one resistor remains open the total circuit resistance increases.
