Why the cable to an electric cooker is thicker than the cable to a table light?
Since resistance is inversely proportional to the cross-sectional area of a wire, thicker the wire - lesser the resistance and vice-versa. Now, according to Joule's law of heating, H = I^2 R t; i.e. H (Heat) is directly proportional to the square of I (Current), R(Resistance) and t (time). Whereas, according to Ohm's law, V=IR; i.e. V (Potential difference) is directly proportional to I (Current) and R (Resistance) Comparing both the formulas, we can conclude that H (Heat) needs more Current; I. [H=I^2 R t] Therefore, thicker wire. Hence, the cooker needs a thicker wire while a table light needs a comparatively thinner wire.
What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
Can light travel through the core of a fiber optic cable?
yes, the ability of light to travel through the cable is what makes it useful. There is not some sort of hole in the center of the cable, it is a solid glass cable.
What is submarine cable buoy light and buoy?
what is submarine cable buoy light and shape & what is submarine emergency buoy light and shape
How does light travel through fiber optic cable and what are the factors that influence its transmission?
Light travels through fiber optic cable by bouncing off the walls of the cable in a process called total internal reflection. The factors that influence its transmission include the quality of the cable material, the purity of the light source, the distance the light travels, and any obstacles or bends in the cable that may cause signal loss.
How does data travel through a fiber optic cable?
Data travels through a fiber optic cable using light signals. These signals are sent through the cable as pulses of light, which represent the data being transmitted. The light signals bounce off the walls of the cable, allowing the data to travel quickly and efficiently over long distances.
What is the form of the signal in twisted pair cable and coxial cable?
Twisted pair wiring is a digital signal.Coaxial cable is an analog signal.
Cable is used to connect different devices?
cable used for networking are coaxial cable,twisted pair cable,fibre optic cable twisted pair is divided in networkinn shielede and un shielded utp cable is most commenly used in networking, but optic fibre travel speed of light so it is very fast compaired to other cable so most commpany use optic fibre cable in order to aviod data loss cable used for networking are coaxial cable,twisted pair cable,fibre optic cable twisted pair is divided in networkinn shielede and un shielded utp cable is most commenly used in networking, but optic fibre travel speed of light so it is very fast compaired to other cable so most commpany use optic fibre cable in order to aviod data loss
What kind of Cable transmit signals as pulses of light over glass strands inside protected tubing?
Fiber optic cable.
Different between fiber optical cable and copper cable?
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
Why does 2002 Jeep Wrangler dash brake light blink?
Check the emergancy brake cable- as it starts to wear, it stretches & leaves slack in the cable. There should be an adjustment to remove this slack. The tension in the cable pulls the lever to not make the switch for the brake light come on.
Which type of cabling is easiest to install?
In computer networking, the type of cabling that is easiest to install is coaxial cable. It is a light, inexpensive and flexible cable.
