Question

What is the resistance and temperature coefficient of resistance of a resistor if its color code is yellow-green-blue-violet-red-yellow?

Answer 1

Resistance

V=iR

$R=R_0(1+\alpha(T-T_0))$

$$R=45\times10^6+45\times10^6\times\frac{5}{100}=45\times10^{6}[1+0.5]$$

$$R=72\times10^4+72\times10^4\times\frac{5}{100}=72\times10^{4}[1+0.5]$$
