What method of heat transfer does a campfire use?

What method of heat transfer does a campfire use? Radiation Is a campfire convection? There are three basic ways in which heat is transferred: convection, conduction and radiation. A campfire is a perfect example of the different kinds of heat transfer. If you boil water in a kettle, the heat is transferred through convection from […]

What does a trouble code indicate?

What does a trouble code indicate? DTC’s, or Diagnostic Trouble Codes, are used by automobile manufacturers to diagnose problems related to the vehicle. They are how the OBD-II (in light duty vehicles) or J1939 (in heavy duty vehicles) identifies and communicates to technicians where and what on-board problems exist. How do you read trouble codes? […]

What is a potential hazard to your head?

What is a potential hazard to your head? Potential Hazards: Head trauma from falling objects. Bumping the head against fixed objects. Electric shock and burns from contact with exposed electric conductors. What are the hazards when welding? Health hazards associated with welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) […]

What is the atomic packing factor for BCC?

What is the atomic packing factor for BCC? Body-centered cubic Because the volume of each of the eight corner atoms is shared between eight adjacent cells, each BCC cell contains the equivalent volume of two atoms (one central and one on the corner). What is the packing fraction of BCC unit cell? They occupy the […]

How does op amp increase slew rate?

How does op amp increase slew rate? The slew rate of an OTA or op-amp is proportional to the maximum current, usually available from the first stage of the circuit. Increase in the slew rate requires increase in the value of bias current source, which will increase the overall power dissipation of the circuit. How […]
