The current flowing through a resistor connected in a circuit and thepotential difference developed across its ends are as shown in thediagram by milliammeter and voltmeter readings respectively :(a) What are the least counts of these meters ?(b) What is the resistance of the resistor ?200100 This++mA

Answer»

(a) Least count of milliammeter = 100/10 = 10 mALeast count of voltmeter = 1/10 = 0.1 V(b) Voltmeter reading = 2+(4*0.1) = 2.4 VMilliammeter reading = 200+(5*10) = 250 mAResistance = V/I = 2.4V / 250mA= 96 ohm

Hope it helps.Mark as best if I am correct.

96 is the answer ok.

96 is the answer ok.........
