A potentiometer circuit is set up as shown. The potential gradient across the potentiometer wire, is `k` volt/cm and the ammeter, present in the circuit, reads `1.0` A when two way key is switched off. The balance points, when the key between the terminals (i) 1 and 2 (ii) 1 and 3, is plugged in, are found to be at lengths `l_1 cm and l_2 cm`, respectively. The magnitudes of the resistors `R and X` in ohm, are then, respectively equal
Repeater Machine Similarly, repeater machine is a hypothetical machine which automatically enlarges items several times. For example, sending a piece of wire through a `(xx 2^4)` machine is the same as putting it through a (xx 2) machine four times. So, if you send a 3 cm piece of wire through a `(xx 2^4)` machine, its length becomes `3 xx 2 xx 2 xx 2 xx 2 = 48` cm. It can also be written that a base (2) machine is being applied 4 times. What will be the new length of a 4 cm strip inserted in
