NettetTransistor two-LED flasher circuit operates at about 1Hz. Here, Q1 and Q2 are wired as a simple 1Hz astable multivibrator, in which Q1 and LED1 turn on as Q2 and LED2 turn …

Nettet29. okt. 2024 · Capacitance C = Q/V, Q – charge stored in the capacitor, V – voltage across the plates. Hence, the capacitance of a capacitor is the ratio of stored charge to … NettetA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.

NettetWe now need to check the power rating of the resistor when the flasher is on. Power is given by P = V 2 R so let's say we want the LEDs very dim when off so we add 1k in parallel and we'll have 58 V across the resistor when on. P = V 2 R = 60 2 1000 = 3.6 W. Obviously a 0.25 W resistor isn't going to be good enough.

Nettet30. sep. 2016 · 1 Answer Sorted by: 1 The LM358 might swing its output to within 2V of the supply rail on a good day. That means on a 4V supply it might be able to muster 2V on the output. It barely reaches half Vcc in other words.
