Web1st step. All steps. Final answer. Step 1/2. To determine the current flowing through resistor R4, we need to use Kirchhoff's laws and Ohm's law. First, we can use Kirchhoff's voltage law (KVL) to find the total voltage drop across the circuit. KVL states that the sum of the voltages in a closed loop must equal zero. View the full answer. WebA current limiting resistor regulates and reduces the current in a circuit. This equation and calculator helps determine the value of the resistor to add to a light-emitting diode (LED) so that it can limit the current moving through the LED. The calculation also determines how much power the LED consumes.
