Q

Question 24

What are the factors affecting resistance?

Answer 24

• Length
• Cross-Sectional Area
• Material (Resistivity)
• Temperature

Question 25

Formula of Temperature Coefficient

Answer 25

a = 1/(T + t); wherein a is alpha

Question 26

Which of the factors is inversely proportional to resistance?

Answer 26

Cross-Sectional Area

Question 27

Formula of Temperature in relation with Resistance

Answer 27

Rsub2 / Rsub1 = 1 + alpha (tsub2 - tsub1)
or
Rsub2 / Rsub1 = (T + tsub2) / (T + tsub1)
