Answer:
add resistance to a circuit
Explanation:
It depends on the design in which it is incorporated. A fixed resistor has many uses, including, but not limited to ...
- dropping voltage
- limiting current
- contributing to a time delay
- adjusting frequency response
- eliminating (or creating) signal reflections
- acting as a fuse
- calibrating or trimming a response
- providing protection against electrical shock or ESD
- acting as a reference when measuring variable resistors
Answer:
4. Making a few tacos and eating them to see how they taste.
Explanation:
The method of engineering design refers to the sequence of procedures that engineers undertake to reach a solution to a concerning problem. Generally, the solution needs to create a machine or a product that fulfills specific requirements or performs a specific function. the step of testing and redesigning includes engineers to test their final design so that they can make change their solution to enhance it, based on their feedback and their experience with the solution. As per the question eating tacos will provide the appropriate feedback to make final changes to the tacos.
Answer:
Recycling.
Explanation:
Recycling can be defined as the process of gathering, processing and conversion of waste materials such as thrash or scraps into new materials or products. Thus, recycling facilitates the reuse of materials that could have been disposed off as waste or thrash.
Hence, recycling is a process which applies to cleaning refrigerant for immediate reuse by oil separation and single or multiple passes through devices, like replaceable core filter driers, which reduce moisture and acidity. This simply means that, refrigerants can be cleaned for reuse by using an oil separation technique to remove the residual refrigerant oil and then a filter-drier to reduce moisture and acidity.
Answer:
Heat transfer for a internally reversible process.
Explanation:
Internally reversible means that there is entropy generation ' with in ' the system.
Heat transfer of a process is considered to be reversible if it occurs because of any minute temperature difference between the surrounding and the system .
Let us consider an example ,
Transferring of the heat across the difference in temperature of 0.0001 °C appears as more reversible than for the difference in temperature of 100 °C .
Hence ,
By heating or cooling a system for a number of infinitesimally small steps , we can approximate a reversible process.
