"WebbThis 250 \,\Omega 250Ω resistor has been labeled using the sign convention for passive components. The voltage polarity (orange signs and arrow) have been assigned with + + at the top of the resistor. This direction was an arbitrary choice. The blue current arrow points into the positive terminal. This was not an arbitrary choice. " - Problems on resistors

Webb16 mars 2024 · I = I 1 + I 2 + I 3. Potential Difference across all both Resistors remain the same (as they are both between Same points) Hence we can say that. Potential Diff=V. It is same for both Resistor 1 and Resistor 2. Now we know that as per Ohm's Law. Potential Diff=Current*Resistance. Potential Difference/Resistance=Current. WebbExplanation: The resistors are linked together at both ends in a parallel combination. Therefore, across the resistors, the potential difference will not change and thus, remains the same. 5) Two wires having their radii in ratio 6:3, but the same length and same material are combined in series.
