Q. No.AB is a \(20\) \(\Omega\) resistor with a tapping point C that can be moved along AB. The resistances in AC, BC are proportional to the lengths AC, BC. Initially, C is at the mid-point of AB and the circuit is switched on.
If the tapping point C is moved so that the length BC is reduced to half its initial value, then the voltage across the \(15\) \(\Omega\) resistor,
If the tapping point C is moved so that the length BC is reduced to half its initial value, then the voltage across the \(15\) \(\Omega\) resistor,
