Consider two meters A and B. Meter A has a range of (0 - 150) V and multiplier resistance of 50 kQ. Meter B has a range of (0 - 500) V and a multiplier resistance of 180 kQ. Meter A and B have basic meter resistances of 1 kQ and 2 kO respectively. Determine which meter is more sensitive?

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

Answer the following questions: A d’Arsonval movement has a full-scale deflection at 25 milliamperes, and the coil has a resistance of 2 ohms. What is the resistance of the multiplier require to convert this instrument into a voltmeter with a full-scale deflection at 300 volts? What is the resistance of the shunt required to convert this instrument into an ammeter with a full-scale deflection of 25 amperes.
