How to Calculate The wavelength?
To put this into perspective, we need to express the distance traveled by a voltage or current signal along a transmission line in relation to its source frequency. An AC waveform with a frequency of 60 Hz completes one cycle in 16.66 ms. At light speed (186,000 mile/s), this equates to a distance of 3100 miles that a voltage or current signal will...
What Happens If The Transmission Line Is “Short”?
When an electrical source is connected to a load via a “short” transmission line, the load’s impedance dominates the circuit. This is to say, when the line is short, its own characteristic impedance is of little consequence to the circuit’s behavior. We see this when testing a coaxial cable with an ohmmeter: the cable reads “open” from center condu...
What Happens When The Transmission Line Is Electrically “Long”?
When a source is connected to a load via a “long” transmission line, the line’s own characteristic impedance dominates over load impedance in determining circuit behavior. In other words, an electrically “long” line acts as the principal component in the circuit, its own characteristics overshadowing the load’s. With a source connected to one end o...
What is the difference between 60Hz and 50Hz?
The obvious difference is the difference in frequency. The 60 Hz is 20 % greater than the 50 Hz frequency. This 20% difference plays a huge difference for an appliance. For power generation, the generator turbine needs to be rotated at a certain speed to generate the desired frequency.
What is the synchronization frequency of a TV?
50 Hz power hum 60 Hz power hum 400 Hz power hum Most countries chose their televisionvertical synchronizationrate to be the same as the local mains supply frequency.
How long does a 60 Hz power line have to be?
For a 60 Hz AC power system, power lines would have to exceed 775 miles in length before the effects of propagation time became significant. Cables connecting an audio amplifier to speakers would have to be over 4.65 miles in length before line reflections would significantly impact a 10 kHz audio signal!
How long is a 100 MHz radio signal?
Consider a 100 MHz radio signal: its wavelength is a mere 9.8202 feet, even at the full propagation velocity of light (186,000 mile/s). A transmission line carrying this signal would not have to be more than about 2-1/2 feet in length to be considered “long!” With a cable velocity factor of 0.66, this critical length shrinks to 1.62 feet.
