Expert Solution & Answer
Check Mark
To determine

Three main electrical test instruments used in trouble shooting.

Explanation of Solution

An industrial electrician's main job is to troubleshoot or restore a control circuit when it fails. First, it is necessary to determine which component is at fault in order to repair or remove a faulty component. Three main instruments used to troubleshoot a circuit are the voltmeter, ohmmeter, and ammeter. They can measure several different electrical quantities, so this meters are called multimeters.

Thus Voltmeter, Ohmmeter, Ammeter are the main electrical test instruments used in trouble shooting.

Consider the following acid-base reaction: Fe3+(aq) +3H2O -Fe(OH)3 (s) + 3H* ← A. Using thermodynamics, calculate the equilibrium constant K at 25°C (The AG° of formation of Fe(OH)3(s) is -699 kJ/mol). B. Using the value of K you calculated in part a, if a solution contains 10-4 M Fe3+ and has a pH of 7.5, will Fe(OH)3(s) precipitate? Show all calculations necessary to justify your answer. Note that the reaction as written is for precipitation, not dissolution like Ksp-
