Hint: To identify and calculate approximate values of resistors, they are colour coded. This means that every colour denotes a specific value of resistance. To understand the value of resistance of a specific resistor, we need to first thoroughly understand the concepts of colour coding in resistors. Keeping this in mind, we can approach such questions with ease.
Complete step-by step answer:
From the colour code table, we can determine the colour codes of the various colours mentioned in the resistor. Therefore, we can determine that;
Brown = 1,
Yellow = 4,
Green = ${{10}^{4}}$ and
Gold = $\pm 5\%$
Now,
From the given question we can easily calculate the resistance of the given resistor as
$=14\times {{10}^{5}}\pm 5\%$
Hence, the correct answer is Option A.
Note:We must keep in mind the tolerance level given in percentage after every value which is denoted in gold or silver colour. It indicates the tolerance level of the resistance in case of voltage spikes. Moreover, we must always remember the order in which the resistance table is given in order to effectively calculate the resistance of the resistor.
