Testing the PCB Transistor In circuits, transistors play a crucial role, thus it’s crucial to make sure they’re functional. When they are flawed, the circuit fails as a result. Because of this, it is crucial that you test them in order to make sure they are operating as intended. Be...
The diode which needs to be tested in the circuit can be arranged in between two points like A & B which is shown below. This circuit can be worked through dual 9V batteries and it works in two cases which are discussed below. In the first case, the anode terminal of the diode is c...
Transistors are basically of two types:bipolar junction transistor(BJT), andmetal–oxide–semiconductor field-effect transistor(MOSFET) For a BJT, the 3 terminals are designated as base, emitter, collector. A low power signal across base/emitter terminal allows the transistor to switch a comparativel...
In this post I have explained the method of correctly replacing a BJT with a MOSFET, without affecting the final outcome of the circuit. Contentshide 1Introduction 1.1Difference Between BJT and MOSFET 1.2BJT Base Resistor vs MOSFET Gate Resistor 1.3How to Replace a Transistor (BJT) with a MOSF...

Never perform continuity test in Live Wire or Circuit. Switch OFF and Unplug the Device to be Tested. Make Sure there is NOVoltagein the Circuit to be Tested. Make sure that allCapacitorsare Discharged. Check:How to Test a Transistor with a Multimeter?
Distributor based ignition systems use a single ignition coil. The switching of the primary circuit can be controlled using one of two mechanisms: mechanically, by a contact breaker driven by a rotating cam within the distributor. using transistorised current switching, triggered by a timing referen...
MOSFET Testing In-Circuit Versus Out-of-Circuit Common MOSFET Faults and How to Identify Them Troubleshooting MOSFETS What is the MOSFET? A metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOSFET) is a type of field-effect transistor (FET), most commonly fabricated by th...
The transistor is one of the basic semiconductor components, which has the function of current amplification and is the core component of the electronic circuit. The transistor is made of two PN junctions very close to each other on a semiconductor substrate. The two PN junctions divide the whol...
Step 14: Measuring Capacitors - a 10μF Barrel Capacitor Step 15: Measuring Transistors: a Bipolar Junction Transistor (BJT) - NPN I won't pretend to know anything about these, except to put the right ones in the right place as directed by smarter people. However, this example shows the...
