a = δV/δT.

V1 = 10 V.
T1 = 25 c.
V2 = 10.2 V.
T2 = 100 c.

Then temperature coefficient is = [{(V2-V1)/V1}/(T2-T1)]*100.

= [(10.2-10/10)/(100-25)]*100.

= 0.0267 V.

How it can be solved?

V(T) = V(1+B(t2-t1)).

Where B is the coefficient.

Given:

vz = 10v.
Vo = 10.2v.
Tf = 100c.
Ti = 25c.

Download:

Tc = (vf-vi)/(tf-ti).
Tc = (10.2-10)/(100-25).
Tc = 0.2/75.
Tc = 0.0267.

Proper formula please?

Sreeyush Sudhakaran said:   1 decade ago
Tempcoeff=(change in voltage/change in temp)x voltage at inital temperature
=(10.2-10)/(100-25) x 10
= 0.2/75 x10
=0.026666... = 0.0267

Tcoeff=(change in voltage/change in temp)*voltage at inital temp
Here initial temp is 25degc & voltage is 10v

Selvamuthu said:   1 decade ago
Tcoeff = change in voltage/(change in temp * voltage at (TO))
TO initial temp ie 25 deg c in this problem.
