It'a REALTIME ONLINE calculator!
Out targets are Hardware, pcb, system engineer
You may use metric Prefixies(like k, m,u,n,p,...).
It converts frequency to wavelength and wavelength to frequency.
The higher the dielectric constant, the lower the propagation speed.
Low-pass filter Frequency at which the voltage becomes -3dB (0.707x)
The voltage at the midpoint when the voltage is divided by the resistor is determined.
In actual design, the voltage at the midpoint will not be constant due to errors in resistance and voltage.
Design a circuit consisting of a power supply, LEDs, and resistors.
The actual components have variations in resistance and Vf, so there will be errors in the LED current.
Power consumption From current and voltage
Calculates the efficiency of the power supply from the input voltage and current and the output voltage and current.
Inverting amplifier circuit of OP amplifier
Find the capacitance of the capacitor that can store the pulse current.
Calculate the electricity rate from the rated power consumption (xxW). 1kW = about 20 yen.
This is a calculator to convert the discharge capacity in mAh notation that you often see in batteries to power consumption (xxW).

The reference voltage is often conventionally 3.7V.
Calculate the amount of voltage drop from the resistance and current values.
This is a easy calculation and no guarantee is given for the calculation results.
