Q. A resistor has bands with colours orange, green, silver and gold. Then the resistance of the resistor is

$(350 \pm 5) m Ω$

$(350 \pm 17.5) m Ω$

$(35 \pm 5$

$(250 \pm 5$

Given, orange $= 3$ ,
Green $= 5$
Silver $= 1 0^{- 2}$
Gold (tolerance) $= \pm 5%$
From colour code, resistance value is
$[35 \times 1 0^{- 2} \pm 5%]$
$= 350 \times 1 0^{- 3} \pm 5%$ ohms
$= 350 m - Ω \pm 17.5 m - Ω$

Q. A resistor has bands with colours orange, green, silver and gold. Then the resistance of the resistor is

(350±5)mΩ

(350±17.5)mΩ

(35±5

(250±5

Given, orange =3, Green =5 Silver =10−2 Gold (tolerance) =±5% From colour code, resistance value is [35×10−2±5%] =350×10−3±5% ohms =350m−Ω±17.5m−Ω

$(350 \pm 5) m Ω$

$(350 \pm 17.5) m Ω$

$(35 \pm 5$

$(250 \pm 5$

Given, orange $= 3$ ,
Green $= 5$
Silver $= 1 0^{- 2}$
Gold (tolerance) $= \pm 5%$
