\(\mathit{P} = \frac{RA}{l}\)
\(\mathit{P} = \frac{l}{RA}\)
\(\mathit{P} = \frac{Rl}{A}\)
\(\mathit{P} = \frac{R}{Al}\)
Correct answer is A
resistivity P is directly proportional to the product of resistance and cross-sectional area and inversely proportional to the length of the wire
0.0167\(\Omega\)
0.0130\(\Omega\)
0.0250\(\Omega\)
0.1000\(\Omega\)
Correct answer is A
\(R_2 = \frac{I_1R_1}{I_2} = \frac{0.01 \times 5}{2.99}\)
= 0.0167
