Cylindrical rods of various lengths and cross-sectional areas are made of different materials. Each rod is connected individually to the same battery, whose potential difference is known, and the current in the circuit is measured. Can the resistivities of the rods be compared
Answers: 1
Thus we have V and I values, and if length (L) or cross-section zone could be specified (A) So, you can compare that resistivity, that's why the above-given answer is correct. Another question on Physics
