voltage across R has to be measured with a voltmeter. What percentage error is expected in measuring the voltage if R₁=R₂=R3=R₂=R-100 Q for meter resistance of 1500 Q and 15000 Q. Also calculate the percentage error in measuring the current through R, if the ammeter resistance is 15 and 1.5 Q. Assume Eo, lo as true value and Em, Im as measured value. 10: F 20 20 I' R₁ R₂ R3 ARA A Rg J B 1500022 ģiseen 15000
