WebThe IV graph for a resistor shows that current is directly proportional to potential difference. The IV graph for a bulb shows that as the potential difference increases the current increases. However, at large potential differences a change in potential difference causes a smaller increase in current for a change at small potential differences . WebFixed Resistors & Wires. The current through a fixed resistor or a wire increases as the potential difference (or voltage) across it increases; In other words, current is directly …
