How does a voltage divider work with a resistor and capacitor in an RC circuit?

In summary, a voltage divider is an electronic circuit that divides a higher voltage into a lower voltage using a series of resistors. It works by using two or more resistors in series and the output voltage can be calculated using the formula Vout = Vin * (R2 / (R1 + R2)). A voltage divider has various applications in electronics such as providing a reference voltage, setting bias voltage, and creating stable voltage sources. To calculate the values of resistors in a voltage divider, you need to know the desired output voltage, input voltage, and the resistance of one of the resistors.

Is it possible to make a voltage divider split a DC power input between a resistor and capacitor? If so, does anyone have a good way to calculate vout as a function of time? Thanks :D

1. What is a voltage divider?

A voltage divider is an electronic circuit that divides a higher voltage into a lower voltage using a series of resistors. It is commonly used in electronic devices to provide a specific voltage to a component.

2. How does a voltage divider work?

A voltage divider works by using two or more resistors in series. The voltage across each resistor is proportional to its resistance, so the total voltage drop across the resistors will be divided between them. By choosing the appropriate resistances, a specific voltage can be obtained at the output of the voltage divider.

3. What is the formula for voltage divider?

The formula for voltage divider is Vout = Vin * (R2 / (R1 + R2)), where Vout is the output voltage, Vin is the input voltage, R1 is the resistance of the first resistor, and R2 is the resistance of the second resistor.

4. What are the applications of a voltage divider?

A voltage divider has various applications in electronics, including providing a reference voltage for analog sensors, setting the bias voltage for transistors, and creating a stable voltage source for electronic circuits.

5. How do I calculate the values of resistors in a voltage divider?

To calculate the values of resistors in a voltage divider, you need to know the desired output voltage, the input voltage, and the resistance of one of the resistors. The other resistor's resistance can then be calculated using the formula R2 = R1 * (Vout / (Vin - Vout)).
