RC circuits are fundamental electronic components used for filtering, timing, and signal processing applications.
An RC circuit consists of a resistor (R) and a capacitor (C) connected in series or parallel.

In a charging circuit, the voltage across the capacitor increases exponentially, while in a discharging c...
Latch is level triggered, while flip-flop is edge triggered. Latch is asynchronous, while flip-flop is synchronous.
Latch is level triggered, meaning it changes output when the input signal is high or low continuously.
Flip-flop is edge triggered, meaning it changes output only on the rising or falling edge of the clock signal.
Latch is asynchronous, meaning the output changes as soon as the input changes.
Flip-flop i...
To find the voltage through a resistor, use Ohm's Law: V = I * R
