In (Figure 1), the wire connecting the positive battery terminal to the top end of the resistor is 100 mm long, and the wire connecting the negative battery terminal to the bottom end of the resistor is also 100 mm long. The resistor is 10 mm long,
Select the correct conclusions from the comparison of the resistances of the resistor and he wire segments connecting he battery and the resistor.
-Correct statement-
· The resistances of the wire segments connecting the battery and the resistor can be assumed negligible compared to the resistance of the resistor, therefore the potential differences across he wire segments are negligible compared to the potential difference across the resistor, and the electric field magnitudes inside the wire segments are negligible compared to the electric field magnitude in the resistor, so it can be claimed to a good approximation that Ea=0 and Eb=0 compared to the electric field magnitude in the resistor.
