Correct answer is D
pt = ml 80
90 x 5 x 60 = 160 x L
L = \(\frac{27000}{160}\)
= 168.75Jg-1
= 168.75
Using the data in the circuit illustrated above, calculate the value of R
0.02\(\Omega\)
0.05\(\Omega\)
5.00\(\Omega\)
20.00\(\Omega\)
50.00\(\Omega\)
Correct answer is E
R = \(\frac{V}{T} = \frac{2v}{40 \times 10^{-3}}\)
= 50.00\(\Omega\)
