98. In the folowing circuit, the resistance of the voltmeteris 10,000 Ω and that of the ammeter is 20 Ω . If thereading of the ammeter is 0.1 A and that of the 10voltmeter is 12 V, then the value of R is :-(1) 122 Ω(2) 100 Ω(3) 118Ω(4) 116210 |

Answer» reading in the Voltmeter will give the potential difference across combination of R and A so, V = 12v , and since current is 0.1A so, 12 = 0.1(R+20) => 120 = R+20=> R = 120-20 = 100Ω option 2 |
