Question
Chapter 4, Problem 1RQ
To determine
Whether the given statement “The reading of an analog ohmmeter scane is done from left to right” is true or false.
Expert Solution & Answer
Answer to Problem 1RQ
The given statement is false.
Explanation of Solution
Introduction:
The device that helps in measuring the resistance of the circuit or the component of the circuit is called Ohmmeter. There are two types of ohmmeters.
- Digital Ohmmeter
- Analog Ohmmeter
An analog ohmmeter is an instrument that displays the reading with the help of a needle that points towards the marking on the ohmmeter. It measures the reading from the right to the left. The readings obtained from the ohmmeter are not very precise. Before using an ohmmeter, the circuit should be disconnected from the regular power source; otherwise, it may result in damage to the ohmmeter and injury to the user.
Conclusion:
Therefore, the given statement is false.

One lane of the three lanes on a section of this freeway will have to be closed to undertake an emergency bridge repair that is expected to take 2 hours. It is estimated that the capacity at the work zone will be reduced by 30 percent of that of the section just upstream of the work zone. The mean free flow speed of the highway is 70 mi/h and the jam density is 150 veh/mi/In. If it is estimated that the demand flow on the highway during the emergency repairs is 85 percent of the capacity, using the deterministic approach, determine the following.
