NOTE:LEDs are what's known as a "non-ohmic" devices. This means that the equation for the current flowing through the LED itself is not as simple as V=IR. The LED introduces something called a "voltage drop" into the circuit, thus changing the amount of current running through it. How...
When resistors are connected in series, the current flowing in the circuit will be the same at every point in the circuit. Therefore, by using Ohm’s law, V2 = IR2 ∴ V2 = 0.2 x 15 = 3V Therefore, the potential difference across the 15 Ohms resistor is 3V. ...

PCB trace resistance equation — Ohm's law made practical When it comes to calculating the resistance of a material, Ohm's Law should be the first thing that comes to mind. However, its basic form (R=VIR=IV) is not always very useful. For example, if, during the design phase, we wa...
third quartiles, and the upper and lower whiskers to the maximum and minimum values (no further than 1.5x interquartile range). Outliers are shown with black circles, and yearly mean scores with red squares. A best-fit linear trendline with its equation and R-squared value is shown in red...
