Therefore, we cannot use this transistor to connect loads that consume more than 200mA. The maximum amount of current that can flow through the collector pin is 200mA. The 2N3904 is an NPN transistor, so when the base pin is grounded, the collector and emitter will remain open (reverse biased), and shorted (forward biased) when a signal is supplied to the base pin. Therefore, in this project, we will use 3 2N3904 NPN transistors to design a simple timer circuit. Without the specified delay introduced by this circuit, the device may malfunction or even be damaged. This delay of several seconds or minutes becomes a key requirement to ensure the correct operation of the circuit. A simple timer circuit is a key part of any electronic circuit that introduces a set time delay in various switching devices.
