Consider the scale of a voltmcter shown in the diagram and answer thefollowing questions:1-53.0(a)What is the least count of the voltmeter?(b)What is the reading shown by the voltmeter?(c)If this voltmeter is connected across a resistor of 20 立, how muchcurrent is flowing through the resistor ? |

Answer» (a) Least count = Value measured in n divisions/n= 1.5/10 = .15 volts (b) The reading shown by voltmeter = 1.5 +.3 = 1.8 volts (c) V = I * R V = 1.8 R = 20 ohm Therefore, I = 1.8/20 = .09 ampere |
