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

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

Write down the practical unit of resistance.

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.

With two resistances 2 Omega and 3 Omega In parallel a third resistance of 4 Omega is connected in series.Find their equivalent resistance.

There are 14 resistances each of magnitude 1 Omega . Keeping three of them in series in each row,four rows are arranged in parallel. The remaining two resistances are connected in series with the previous combination.Determine the equivalent resistance of the whole network.

A uniform copper wire of resistance R is halved and the two parts are connected in parallel .IF now the equivalent resistance is R' then what is the ratio of R to R'?

If ‘n’ no .of Resistance R are connected in series and then in parallel combination to get the equivalent resistance X and Y, then what is the relation between Y, X and R-

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.

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