The following measurements of current and potential difference were made on a resistor constructed of Nichrome wire:
I(A) | 0.50 | 1.00 | 2.00 | 4.00 |
Vab(V) | 1.94 | 3.88 | 7.76 | 15.52 |
(a) Graph Vab as a function of I. (b) Does Nichrome obey Ohm’s law? How can you tell? (c) What is the resistance of the resistor in ohms?
We need at least 10 more requests to produce the solution.
