Trickle charging is the concept of charging a fully charging battery with current that is equivalent to battery's self discharge rate
Ideal Opamp possess infinite bandwidth, infinite open loop gain, infinite input impedence and zero output impedence
Every battery possess internal resistance, this internal resistance should be very low to deliver maximum current to the load
When operating SCR as a switch in forward biased mode, forward current will not pass through unless trigger gate current is supplied.
Power dissipation in a resistor will occur in the form of heat
Working of a relay takes place when current flows through the coils in a relay it gets magnetized and attracts the switching pole to ON position.When current flow through the relay stops pole reverts back to OFF position.
Exchange of ions within vegetables such as Potato, Lemon, Cucumber etc can generate minimal current.This is the science behind potato clock
Loading effect is a phenomenon which occurs when a low impedance load is connected to high impedance source which results in high current draw by load and therefore voltage across the source drops significantly
Negative feedback controls the gain in amplifier and stabilizes the signal whereas positive feedback increases the gain and introduces hysteresis
Latches act as a memory element by remembering the output state from previous inputs
Mechanical switches are not perfect in nature.Switch bouncing refers to the instance when a single press of mechanical push button emits series of multiple pulses thus introducing error in digital circuits.Switch debouncing mechanism should be used along with mechanical switches to prevent this.
