Consider the circuits shown in the figure. Both the circuits are taking same current from battery but current through R in the second circuit is th of current through R in the first circuit. If R is 11 Ω, the value of R1
(1) 9.9 Ω
(2) 11 Ω
(3) 8.8 Ω
(4) 7.7 Ω
(1) In figure (b) current through
Potential difference across R2 = Potential difference across R ⇒ i.e.
Total circuit resistance ⇒
