Well.. But it does not answer my question..which was to know if there is a way of measuring p.d. across 2 points in a circuit other than using a volmeter and to measure current without an ammeter.. .. There certainly is a way cos..Ohm obviously wouldn't have used a votmeter or an ammeter(cos we...

Is there anyway of measuring the potential difference between 2 points on a electrical circuit other than using a voltmeter? The reason I'm raising this question is because Voltmeters are developed purely using Ohm's Law and so certainly Ohm might have had his own way of measuring the p.d. for...

There is a chief problem.. [SIZE="4"]First of all, How do you know that the rope obeys Hookes law(ie F is proportional to x)? ot all ropes obey the F=kx relation.. In fact only very few of them do..
