Question

If the resistance R,in a circuit changes with the temperature T, following the relation, R=T^2+3T+5,calculate the total resistance from 5 degrees celsius to 10 degrees Celsius

Answer 1

Total Resistance R = 180 Ohms

Explanation:

R=T^2+3T+5

At 5°C,

R = 5² + 3(5) + 5

R = 25 + 15 + 5

R = 45 Ohms

At 10°C,

R = 10² + 3(10) + 5

R = 100 + 30 + 5

R = 135 Ohms

Total Resistance = (45 + 135) Ohms

R = 180 Ohms
