WebDec 9, 2024 · Find the voltage drop of resistor R1 and resistor R2. Solution. Voltage for Resistor R1 = 0.02A x 220Ω. Voltage for Resistor R1 = 4.5V. Since the resistance value of resistor R2 is the same, we can infer the voltage drop for resistor R2 is the same as the voltage drop calculated for resistor R1. Voltage for Resistor R2 = 0.02A x 220Ω

WebCurrent Draw (AMPs) Enter the following values to calculate the Dropping Resistor. Input Voltage - This is the Supply Voltage. Output Voltage - This is the desired Output Voltage. Current Draw - How much does this device draw in AMPs, it's OK to use decimals here so 25 milliamps is the same as 0.025 AMPs, 1/2 Amp would be 0.5 AMPs, etc. http://www.learningaboutelectronics.com/Articles/How-to-reduce-voltage-with-resistors.php
WebPull up and pull down resistors simply pull you to VCC (UP) or ground (DOWN). The pull down is to remove any remaining voltage that still exists when the switch has been disconnected. You don't want stray voltages in your circuit so you put the pull down resistor to take that stray voltage back to ground. Reply. WebFeb 10, 2024 · What is the voltage drop across each resistor? First, calculate total resistance: 4 + 2 + 6 = 12 Ω. Next, calculate the current: 24 V/12 Ω = 2 A. Now, use the current to calculate the voltage drop across …
WebMar 9, 2024 · The voltage drop across the resistor is 9V – 8.5V = 0.5V, so you get: There is 0.05 mA flowing through the resistor, and thereby also through the input pin down to ground. Again, use Ohm’s law to find the resistance of something with a voltage drop of 8.5 V and a current of 0.05 mA: The input impedance is 170 kΩ.
