Question

If heat dissipated in a resistance can be determined from the relation:H = I2Rt joule , If the maximum error in the measurement of current,resistance and time are 2% ,1% , and 1% respectively, What would be the maximum error in the dissipated heat?​

Answer 1

Answer:

the maximum error in the dissipated heat = 6 %

Explanation:

If heat dissipated in a resistance can be determined from the relation:H = I2Rt joule , If the maximum error in the measurement of current,resistance and time are 2% ,1% , and 1% respectively, What would be the maximum error in the dissipated heat?​

H = I²Rt

ΔH/H = 2ΔI/I  + ΔR/R  + Δt/t

ΔI/I = 2 %

ΔR/R = 1 %

Δt/t =  1%

ΔH/H =  2 (2) + 1 + 1  %

=> ΔH/H = 4 + 1 + 1 %

=> ΔH/H  = 6 %

the maximum error in the dissipated heat = 6 %

Answer 2

Answer:

the max error in Displacement error is 6%

Explanation:

Given- H=I²RT/4.2
