1) (Rev 2/11) Define and discuss the following: electrical charge current and voltage. What are the units of measurement of each?2) (Rev 2/11)In a 60 Hz circuit (such as house wiring) the voltage varies from a maximum value to a minimum and back again 60 times per second. How is the average voltage defined? Why this definition and not just the average voltage?3)(Rev 9/11) For the circuit below find:a) The current through R1 (10 )b) The current through R2 (30 )c) The current at the ammeter M (in amperes)4)For the circuit below find:a) The current through R1 (20 )b) The current through R2 (10 )c) The current through the ammeter MIn general Cases are expected to possess the attributes of precision clarity breadth depth and critical thinking. Not all of these are relevant to the answer to every problem in the case. When an attribute is relevant the evidence for it is as follows.
