Unlike direct current, alternating current reverses direction of flow periodically. Rectifier is a device which converts alternating current to direct current. It does this by cutting off one
In spite of a solar flare yesterday and band predictions being just ‘fair’ as per the Solar Terrestrial Data on QRZ.COM, 20m band is open here early morning.
Electronic components like resistors, capacitors and inductors can be connected together in series or parallel. Components connected in series are connected along a single electrical path and same
2024 CQ World-Wide DX Contest for SSB mode starts at 00:00:00 UTC Saturday, 26th October 2024 and ends at 23:59:59 UTC Sunday, 27th October 2024. Even though I
Phase of a wave is the angular displacement of a sinusoid from a reference point or time. Phase in the context of alternating current can be considered as
Basic electronic components can be divided into passive and active components. Passive devices are resistors, capacitors, inductors and transformers. Active devices are diodes and transistors. Integrated circuits are
While direct current flows only in one direction, alternating current changes direction with a periodicity. Typical mains supply in this region has a frequency of 50 Hz or
Metals like iron, nickel, cobalt and some of their alloys can be attracted by magnets while those like copper, manganese and aluminium are not. A magnetic bar has
