How to calculate Vout for a resistor R2?
The required output voltage (Vout) can be obtained across the resistor R2. Using these two resistors we can convert an input voltage to any required output voltage, this output voltage is decided by the value of the resistance R1 and R2. The formulae to calculate Vout is shown below. Vout= (Vin x R2) / (R1 + R2)
How to calculate the resistance of a series circuit?
(b) Calculate the current through each resistor. (c) Calculate the potential drop across each resistor. (d) Determine the total power dissipated by the resistors and the power supplied by the battery. A simple series circuit with five resistors. Strategy In a series circuit, the equivalent resistance is the algebraic sum of the resistances.
How is the required output voltage ( Vout ) determined?
The required output voltage (Vout) can be obtained across the resistor R2. Using these two resistors we can convert an input voltage to any required output voltage, this output voltage is decided by the value of the resistance R1 and R2. The formulae to calculate Vout is shown below.
How to calculate the power of a resistor?
Another important factor to consider while selecting the resistor values is its power rating (P). Once you know the values of I (based in load), Vin, R1 and R2, add R1 and R2 together to get R TOTAL and use the Ohms law calculator to find out the power (Watts) rating required for the resistors.
What kind of resistor do I need for a switching calculator?
For switching applications, a ¼-watt resistor with 5-% tolerance usually works fine. In order to use this calculator, you will need to know the input switching voltage (Vi), supply voltage Vcc, and the load current iL. Use the Standard Resistor Values chart to find the nearest standard resistor value.
How to calculate Vout in voltage divider calculator?
Vout= (Vin x R2) / (R1 + R2) Where, Vout= Output Voltage Vin=Input Voltage and R1=Upper Resistor R2=Lower resistor. We can use the above voltage divider calculator to calculate any one of the value mentioned in the voltage divider formulae, but now let us learn how this formulae was derived.
How to calculate the output voltage of a circuit?
Input Voltage = Current × (Resistance 1 + Resistance 2) Vin = I × (R1 + R2) (1) Similarly let us calculate for output voltage (Vout), here there is only one resistor (R2) across it hence Output Voltage = Current × Resistance R2
