Keep as many significant figures in as possible. The error will be large when
is raised to the power of four. Also, the real value will be much smaller than
since the emittance of a human body is much smaller than assumed.
Answer:
a) For y = 102 mA, R = 98.039 ohms
For y = 97 mA, R = 103.09 ohms
b) Check explanatios for b
Explanation:
Applied voltage, V = 10 V
For the first measurement, current
According to ohm's law, V = IR
R = V/I
Here,
For the second measurement, current
b)
A linear equation is of the form y = Gx
The nominal value of the resistance = 100 ohms
