Why does sound travel faster in water than air ?
Sound travels faster in water than in air due to differences in the physical properties of the two mediums. The speed of sound depends on factors such as density, elasticity,…
Why do we call a transformer a static device ?
A transformer is referred to as a static device because it operates on the principle of electromagnetic induction without any moving parts in its core or windings during normal operation….
How do an IR transmitter and receiver work ?
Infrared (IR) transmitters and receivers are commonly used in various electronic devices for communication and control purposes. IR communication relies on the transmission of infrared light, which is not visible…
Why are inductors usually in a coil shape ?
Inductors are typically in a coil shape due to several advantageous properties and effects that arise from this configuration. The coil shape, often referred to as a solenoid or coil…
Whats the point of matched pair transistors ?
Matched pair transistors refer to a pair of transistors that are intentionally manufactured or selected to have nearly identical electrical characteristics. These matched pairs are used in various electronic circuits,…
Why is the fuse not used in the neutral ?
Fuses are primarily designed to protect electrical circuits from overcurrent conditions that could lead to damage or fire hazards. In most electrical installations, fuses are placed in the hot (live)…
Why do we need a starter to start a DC motor ?
Starting a DC motor without a starter can lead to several issues, and the use of a starter becomes essential to address these challenges. A starter in the context of…
A diode will conduct in which mode ?
A diode can conduct in two different modes: forward bias and reverse bias. Forward Bias: When a diode is forward-biased, it means that the voltage across the diode allows the…
Can we use electrolytic capacitor for ac ?
Electrolytic capacitors are generally designed for use in direct current (DC) circuits due to their specific construction and characteristics. Using electrolytic capacitors directly in alternating current (AC) circuits is not…
