Many voltmeters are digital, giving readings as numerical displays.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Voltmeters can also provide readings in analog form, by moving a pointer that indicates voltage on a scale, but digital voltmeters generally have a higher order of accuracy than analog instruments.<\/span><\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-11036\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/08\/D.C-Voltmeter.jpg\" alt=\"difference between potentiometer and voltmeter\" width=\"600\" height=\"622\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/08\/D.C-Voltmeter.jpg 600w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/08\/D.C-Voltmeter-289x300.jpg 289w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/08\/D.C-Voltmeter-405x420.jpg 405w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<h3>Working Principle of Voltmeter<\/h3>\n<p><span style=\"font-weight: 400;\">The main principle of a voltmeter is that it must be connected in parallel in which we want to measure the voltage. Parallel connection is used because a voltmeter is constructed in such a way that it has a very high value of resistance. So if that high resistance is connected in series then the current flow will be almost zero which means the circuit has become open.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If it is connected in parallel, then the load impedance comes parallel with the high resistance of the voltmeter, and hence the combination will give almost the same impedance that the load had. Also in the parallel circuit, we know that the voltage is the same so the voltage between the voltmeter and the load is almost the same and hence voltmeter measures the voltage.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For an ideal voltmeter, the resistance is to be infinity,\u00a0 and hence the current drawn is to be zero so there will be no power loss in the instrument. But this is not achievable practically as we cannot have a material that has infinite resistance.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Difference_Between_Potentiometer_and_Voltmeter\"><\/span>Difference Between Potentiometer and Voltmeter<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table style=\"width: 100%; height: 336px;\">\n<tbody>\n<tr style=\"height: 46px;\">\n<td style=\"text-align: center; height: 46px;\"><strong>Potentiometer\u00a0<\/strong><\/td>\n<td style=\"text-align: center; height: 46px;\"><strong>Voltmeter<\/strong><\/td>\n<\/tr>\n<tr style=\"height: 46px;\">\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">A potentiometer measures the emf of a cell very accurately.<\/span><\/td>\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">A voltmeter measures the emf of the cell approximately.<\/span><\/td>\n<\/tr>\n<tr style=\"height: 76px;\">\n<td style=\"text-align: center; height: 76px;\"><span style=\"font-weight: 400;\">The potentiometer does not draw any current from a known emf source <\/span><span style=\"font-weight: 400;\">while measuring current.<\/span><\/td>\n<td style=\"text-align: center; height: 76px;\"><span style=\"font-weight: 400;\">Voltmeters draw current from known emf sources while measuring current.<\/span><\/td>\n<\/tr>\n<tr style=\"height: 76px;\">\n<td style=\"text-align: center; height: 76px;\"><span style=\"font-weight: 400;\">While measuring emf, the resistance of the potentiometer becomes infinite.<\/span><\/td>\n<td style=\"text-align: center; height: 76px;\"><span style=\"font-weight: 400;\">While measuring emf, the resistance of the voltmeter becomes very high but measurable.<\/span><\/td>\n<\/tr>\n<tr style=\"height: 46px;\">\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">In the potentiometer sensitivity is high.<\/span><\/td>\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">The voltmeter sensitivity is low.<\/span><\/td>\n<\/tr>\n<tr style=\"height: 46px;\">\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">It is based on the null deflection method.<\/span><\/td>\n<td style=\"text-align: center; height: 46px;\"><span style=\"font-weight: 400;\">It is based on the deflection method<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Now you know the core <\/span><span style=\"font-weight: 400;\">Difference Between Potentiometer and Voltmeter.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hope you enjoyed the article!
