The RC Circuit Calculator is a free online tool that calculates the characteristic frequency of a circuit using capacitance and resistance. To discover the result as quickly as possible, simply enter the input details and push the calculate button.
What is the best way to find frequency?
The steps to finding the characteristic frequency of an RC circuit are listed below. Follow these guidelines to get the best results for your numbers in less time.
- Step 1: Calculate resistance and capacitance.
- Step 2: Multiply the resistance and capacitance values together.
- Step 3: Multiply the result by 2π.
- Step 4: To check the characteristic frequency, get the reciprocal of the product.
RC Circuit Formula
The RC circuit is made up of a resistor and a capacitor. It is a circuit in which a resistance resistor is coupled in series with a capacitance capacitor.
There are two uses of the characteristic frequency. The RC Circuit is utilised as a capacitor charging time and as a filter. The following is the formula for calculating the RC Circuit's characteristic frequency
f = 1/(2π x R x C)
- Where, R = resistance of the resistor
- C = capacitance of the capacitor
- f = characteristic frequency
The capacitor charge time formula is t = R x C
The frequency of signals that can flow through the circuit is determined by the characteristic frequency, f. Signals with frequencies smaller than f are suppressed by the RC circuit, whereas signals with frequencies greater than f can flow freely. Signals with frequencies around f are still partially transmitted, therefore this is not a clear-cut scenario. The RC filter can be used to filter out low or high frequencies depending on the design. The high pass and low pass filters are these.
When a low pass and a high pass filter are combined, you get a broadband filter that suppresses all sounds below and above certain frequencies. Broadband filters are installed in every piece of music equipment we have.
Capacitor Charge Time Calculator
When we connect the RC circuit to a DC power supply, the capacitor begins to accumulate electric charge and continues to do so until it is fully charged. The time it takes is determined by the capacitance of the capacitor C and the resistance of the resistor R that controls the current, or the amount of charge that enters the capacitor every second.
The longer it takes to charge the capacitor, the higher the capacitance or resistance. The capacitor's charging is an exponential process, indicating that the more charge there is, the longer it takes to gather more. The capacitor charge time is the time it takes to charge the capacitor to roughly 63 per cent capacity. You get roughly 87 percent if you double the time.

RC Circuit Examples
Question 1: In the RC Circuit, the capacitance and resistance are 50 Ω and 20 F, respectively. Find its characteristic frequency?
Given: Resistance R = 50Ω
Capacitance C = 20 F
Characteristic Frequency f = 1/(2π x R x C)
f = 1/(2π x 50 x 20)
= 159.15 x 10^-6 Hz
Hence, the characteristic frequency in RC Circuit is 159.15 x 10^-6 Hz.
