Relay Design and Construction: The Relay Design and Construction is normally divided into the following stages: Selection of the operating characteristics. Selection of proper construction. Design of the contact movement…
Light Units: The total light energy output, or luminous flux (Φs), from a source can be measured in milliwatts (mW) or in lumens (1m), where 1 Im = 1.496 mW.…
Silicon Bilateral Switch: It might be convenient to think of a Silicon Bilateral Switch (SBS) as an SUS with a gate terminal, or as a low-current TRIAC. However, the SBS is…
Silicon Controlled Rectifier Principle Operation: Silicon Controlled Rectifier Principle Operation (SCR) consists of four layers of semiconductor material, alternately p-type and n-type as illustrated in Fig. 19-1(a). Because of its…
Bridge Tied Load Amplifier: All of the power amplifiers already discussed have been single-ended (SE): meaning that they provide power to a load that has one terminal grounded and the…
AC Analysis of BJT Circuits Articles: Coupling and Bypassing Capacitors: Coupling Capacitors – To use a transistor circuit to amplify or otherwise process an ac signal, the signal source must…
Bipolar Junction Transistors Articles: Transistor Operation: pnp and npn Transistor Operation – A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two…
Semiconductor Diodes Articles: PN Junction Diode Working Principle: A PN Junction Diode Working Principle explains about the ability to permit substantial current flow when forward-biased, and to block current when…
