Chapter 60, Problem 1SQ
What are the three main electrical test instruments used in troubleshooting?
Expert Solution & Answer
To determine
List the three main electrical instruments that are used in troubleshooting process.
Explanation of Solution
Discussion:
Troubleshooting is a process in which the cause or source of the problem is to be determined by an electrician. If a control circuit is failed, the electrician determines the source of the circuit’s failure. The electrician can resolve the fault only after successful troubleshooting process.
The three main electrical instruments that are used in troubleshooting process by the electrician are as follows:
- Voltmeter
- Ohmmeter
- Ammeter
The voltmeter, ohmmeter, and ammeter measure the voltage, resistance, and current, respectively.
Conclusion:
Thus, the three main electrical instruments that are used in troubleshooting process are listed.

- 2. (35 points) Use you program to investigative properties of a four step linear pathway. Just extend the model given in question 1 to include an additional two species x2 and x3. You can assume simple irreversible mass-action kinetic on each reaction. I recommend you use the following values for the rate constants: 1 = 0.6; k2 = 1.8; k3 = 0.5; k40.04. This will enable you to more easily answer the following questions. You can also assume that the input is the source X and you can set its value to one. You may find that the plot of the phase change at x3 is broken at -180 degrees because it wraps around. To avoid this you can use the method: phase = np.unwrap(phase) to make sure the phase plot is continuous. [10] i) Compute and show the Bode plots for x1, x2 and x3 with respect to the input Xo. [5] ii) Do you see a pattern with the maximum phase shifts as you move from x₁ to x3? [10] iii) Can you explain this pattern?

The zombie alarm you built goes off as they open the door. You jolt awake to see an alpha-zombie charging through the door. The alphas are zombies that turned all of the zombies in its army. If you can take down this one zombie, all the others pouring into the room should fall as well. Luckily, your group was prepared for this eventuality. Another member of your team has constructed the zombie shocker circuit shown in Figure 5, using some batteries for the voltage source, some rusty metal for the resistors and a coil of wire for the inductor. The switch is just you pulling apart two wires to open the circuit (while holding them by their insulated sheaths). 1. Construct the circuit shown in Figure 15 in the Circuit JS simulator. 2.

Due to channel noise, errors are made. As shown in Figure 4.4, the channel is assumed to be symmetric, which means the probability of receiving 1 when 0 is transmitted is the same as the probability of receiving 0 when 1 is transmit- ted. The conditional probabilities of error are assumed to be each e. Determine the average prob- ability of error, also known as the bit error rate, as well as the a posteriori probabilities.arrow_forward
