Question

Q.9
Two resistors are given R1 = (100 ± 3) Ω R2 = (200 ± 4) Ω. If they are in series then Req is



Choose answer:

(300 ± 7) Ω


(300 ± 4) Ω


(300 ± 3) Ω


(300 ± 1) Ω

Answer 1

Answer:-

• R1=(100 ±3)ohm
• R2=(200 ±4)ohm

Resistors are connected in series

hence

$\boxed{\sf R_{eq}=R_1+R_2}$

$\\ \sf \longmapsto R_{eq}=(100\underline{+}3)+(200\underline{+}4)$

$\\ \sf \longmapsto R_{eq}=100+200\underline{+}3+4$

$\\ \sf \longmapsto R_{eq}=300\underline{+}7\Omega(ohm)$
