Answer the following question:
Three resistances `x_1, x_2 and x_3` are connected in a circuit in different ways. X is the effective resistance. The properties oberved for these different ways of connecting `x_1, x_2` and `x_3` are given below. Write the way in which they are connected in each case.(I-current, V-potential difference, x-effective resistacen)
The potential difference across `x_1, x_2` and `x_3` is the same .
