In a meter bridge experiment balance point is `l_1=40cm` away from point A. Now, if an unknown resistance of `X Omega` is added to `4 Omega` resistance in series then balance point is 80cm from point A. Then value of x is .......

In a meter bridge experiment shown below, the null point is obtained at P. The value of unknown resistance X is 2012 50 cm 1.) E

Two resistances are connected in two gaps of slide wire bridge. The balance point is at 40cm from left end. A resistance X is connected in series with smaller resistance R and balance point shifts to 40cm from right end. What is the value of X if R is 4Omega ?

In a meter bridge the null point is obtained at the middle point of the wire. If in one gap the resistance is 10 Omega , then the value of resistance in the other gap is :–

Two resistances are connected in two gaps of a meter bridge. The balance point is 20 cm from the zero end. A resistance of 15 Omega is connected in series with the smaller of the two. The null point shifts to 40 cm . The value of the smaller resistance in Omega is

Two resistances are connected in the two gaps of a meter bridge. The balance point is 20 cm from the zero end. When a resistance 15 Omega is connected in series with the smaller of two resistance, the null point+ shifts to 40 cm . The smaller of the two resistance has the value.

Two resistances are connected in tow gaps of a Meter bridge. The balance point is 20 cm from the zero end. A resistance of 15 Omega is connected in series with the smaller of the two. The null point shifts to 40 cm. The value of the smaller resistance in ohms is

The resistance in the left and right gaps of a balanced meter bridge are R_(1) and R_(1) . The balanced point is 50 cm . If a resistance of 24 Omega is connected in parallel to R_(2) , the balance point is 70 cm . The value of R_(1) or R_(2) is.
