A standard cell which maintains a constant emf of 1.02 V (for very moderate currents up to a few mA) gives a balance point at 67.3 cm length of the wire. To ensure very low currents drawn from the standard cell, a very high resistance of 600 k\u03a9 is put in series with it, which is shorted close to the balance point. The standard cell is then replace by a cell of unknown emf and the balance point found similarly, turns out to be at 82.3 cm length of the wire.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" id=\"Picture 739\" class=\"alignnone\" style=\"height: 128px; width: 147px;\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/ncert\/12\/physics\/ch03\/image248.jpg\" alt=\"NCERT Solutions class 12 physics Current Electricity\" width=\"147\" height=\"128\" \/><\/p>\n[a]What is the value\u00a0<img decoding=\"async\" style=\"height: 15px; width: 15px;\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/ncert\/12\/physics\/ch03\/image249.png\" \/>\u00a0?<\/p>\n[b]What purpose does the high resistance of 600 <img decoding=\"async\" style=\"height: 18px; width: 25px;\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/ncert\/12\/physics\/ch03\/image250.png\" \/>\u00a0have?<\/p>\n[c]Is the balance point affected by this high resistance?<\/p>\n[d]Is the balance point affected by the internal resistance of the driver cell?<\/p>\n[e]Would the method work in the above situation if the driver cell of the potentiometer had an emf of 1.0 V instead of 2.0 V?<\/p>\n[f]\u00a0Would the circuit work well for determining an extremely small emf, say of the order of a few mV (such as the typical emf of a thermo-couple)?
