Answer 1

Answer:

PLEASE MARK ME AS THE BRAINLIEST

Step-by-step explanation:

Resistor Colour Codes :

Red : 2 ( number ; column )

Green : 5 ( number ; column )

Orange : 10³ ( multiplier ; column )

Silver : 10 ( tolerance % ; column )

The resistance value is (25 × 10³ ohm) ± 10%

Answer 2

the range of its probable resistance.​ is $25 \times 10^3$ ohm ± 10%

Step-by-step explanation:

carbon resistor is coloured with four different bands red, green, orange and

silver respectively.

using

Resistance = (1st Digit x 10 + 2nd Digit) x Multiplier

R = (RED X 10 + GREEN) x ORANGE

R = (2 x 10 + 5) x 1000

R = 25 x 1000

R = 25000 ohm

Since the final band is silver, the tolerance is 10%.

hence ,

the range of its probable resistance.​ is $25 \times 10^3$ ohm ± 10%
