10 resistors of colour code Brown, black, and white are connected in parallel. Then net resistance is
A resistance of unknown value connected across a 45 V supply gives 1 mA current. The color code of the resistor is
A student noted the colour of a resistance reversely as silver, orange, green and yellow. The actual value of resistance is
Colour coding of Resistance
The carbon resistance has normally four coloured rings bands $A, B, C$ and $D$.
Colour bands A and B Indicates the decimal figure.
Colour band C Indicates the decimal multiplier.
Colour band D Indicates the tolerance in per cent about the indicated value. Tolerance represents the percentage accuracy of the indicated value.
To remember the sequence of colour code

Tolerance of Gold is $\pm 5 \%$
Tolerance of Silver is $\pm 10 \%$
Tolerance if no colour $\pm 20 \%$
