The equivalent resistance of a group of resistances is R. If another resistance is connected in parallel to the group, its new equivalent becomes R1 and if it is connected in series to the group, it new equivalent becomes R2. Then

Question

The equivalent resistance of a group of resistances is R. If another resistance is connected in parallel to the group, its new equivalent becomes R1 and if it is connected in series to the group, it new equivalent becomes R2. Then (A) R1 > R or R2 > R (B) R1 < R or R2 > R (C) R1 > R or R2 < R (D) R1 < R or R2 < R

In parallel combination the equivalent resistance is less than the two individual resistances connected and in series combination equivalent resistance is more than the two individual components.

Q. The equivalent resistance of a group of resistances is $R$ . If another resistance is connected in parallel to the group, its new equivalent becomes $R_{1}$ and if it is connected in series to the group, it new equivalent becomes $R_{2}$ . Then

$R_{1} > R$ or $R_{2} > R$

$R_{1} < R$ or $R_{2} > R$

$R_{1} > R$ or $R_{2} < R$

$R_{1} < R$ or $R_{2} < R$

In parallel combination the equivalent resistance is less than the two individual resistances connected and in series combination equivalent resistance is more than the two individual components.

Q. The equivalent resistance of a group of resistances is R. If another resistance is connected in parallel to the group, its new equivalent becomes R1​ and if it is connected in series to the group, it new equivalent becomes R2​. Then

R1​>R or R2​>R

R1​<R or R2​>R

R1​>R or R2​<R

R1​<R or R2​<R
