- 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.
