The higher the current, the higher the voltage drop. In this case, the first diode has a voltage drop of 0.75 V and the second diode has a voltage drop of 0.8 V. This means that the current through the second diode is less than the current through the first diode.<\/p>\n<p>The current through the second diode can be calculated using Ohm&#8217;s law:<\/p>\n<p>$$I = \\frac{V}{R}$$<\/p>\n<p>where $I$ is the current, $V$ is the voltage, and $R$ is the resistance.
