What is the difference between 547 and 548 transistor?
BC547 and BC548 are essentially the same but BC547 has a higher breakdown voltage whereas BC548 has low noise. These are the most general purpose NPN silicon transistors and changing one with the other does not noticably (or otherwise) affect the circuit.
Is BC547 NPN or PNP?
NPN transistor
BC547 -> BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. BC547 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
How do I connect BC547?
Useful Steps
- Place Transistor on a breadboard.
- Connect Emitter to the ground of the battery.
- Add LED & 330 Ohm Resistor to Collector of BC547.
- Connect 1k Resistor and Switch to Base of transistor.
- Power up the circuit with 9V Battery.

How do I test a BC547 transistor with a multimeter?
Here is the conclusion. BC 547 is a NPN Transistor where the 2nd (middle terminal is base) connected to Red (+Ve) test lead of multimeter. At all, Terminal 1 = Emitter, Terminal 2 = Base, and Terminal 3 = Collector (BC 547 NPN Transistor) because, the test result for 1-2 = 0.717 VDC and 2-3 = 0.711 VDC, i.e. 1-2 > 2-3.
Why bc547 transistor is used in water level indicator?
This indicates that the container is full. BC 547 is known as cheap and easy to use transistor which can be used to design a low-cost water level indicator. You can use this device in day to day life to detect the various levels in water in a container.
