WebAnalyzing electric potential difference across a resistor using Ohm’s law. If the current encounters resistance, the electric potential difference decreases according to Ohm’s law. We sometimes call this a voltage drop. Figure 1: Electric potential drop across a resistor. I think that Kirchhoff's junction rule is a bit unclear about the fact that while the … Electric potential difference and Ohm's law review. Calculating resistance, voltage, … WebCurrent tends to move through the conductors with some degree of friction, or opposition to motion. This opposition to motion is more properly called resistance. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow.
