Question
A better of e.m.f.20 V and internal resistance 6Ω is connected to a resister as shown in figure. If current in the circuit is l amp, the ewsistance of the resistor will be :
Options
A.14 Ω
B.16 Ω
C.28 Ω
D.7 Ω
= 1 ⇒ 20 = R + 6 ⇒ R = 14 ΩTopic: Current Electricity and Electrical Instrument·Practice all Current Electricity and Electrical Instrument questions
