Calculate the resistances of two resistor which when connected in a series provide equivalent resistance `5Omega` and parallel provide equivalent resistance `1.2Omega`.

R_1 and R_2 are two resistances they are connected in series Write down their equivalent resistance in each case.

If two resistance are connected in series and parallel give equivalent resistance 12Omega and 5/2 Omega respectively then find their value.

Combination of resistance, equivalent resistance series and parallel combination.

The equivalent resistances of two resistances in parallel combination is one-fourth of their equivalent resistance in series combination.If one of the resistance is 10 Omega then find the other.

The equivalent resistance of two resistances in series is four times the equivalent resistance when they are in parallel. If one of the resistances is R, then what would be the resistance of the other?

IF two resistor are connected in parallel,their equivalent resistance would be less than even the lower resistance of the two -prove it.

There are n number of cells each of resistance R. When they are connected in parallel, the equivalent resistance is Y and when they are connected in series , the equivalent resistance is X. Find the relation between X,Y and R.

Show that when a number of resistance are connected in parallel their equivalent resistance is smaller than the smallest of them .

Equivalent resistances of two resistors in their series and parallel combinations are 10 Omega and 2.1 Omega respectively.Find out the values of two resistances.
