SATHEE: Current Electricity 5 Question 1

Current Electricity 5 Question 1

1. A $200 Ω$ resistor has a certain colour code. If one replaces the red colour by green in the code, the new resistance will be

(a) $100 Ω$

(b) $400 Ω$

(c) $300 Ω$

(d) $500 Ω$

Solution:

Given, resistance is $200 Ω$ .

So, colour scheme will be red, black and brown.

Significant figure of red band is 2 and for green is 5 . When red (2) is replaced with green (5), new resistance will be

$200 o h m \to 500 o h m$
