Which Of These Circuit Schematics Has An Ammeter

This is not a particularly useful graph but will give the learners a chance to practice drawing a bar graph and give them a visual representation of the decrease in current strength as the number of bulbs increases.

Which of these circuit schematics has an ammeter. Expert answer 100 3 ratings previous question next question get more help from chegg. Some materials have low resistance and are conductors. A measuring device used to measure the flow of current within the circuit. To achieve these low resistances ammeter shunt resistors often have to be custom made from relatively large diameter wire or solid pieces of metal.

The ammeter would have the same reading if located between points d and e or between points f and a as it does in the position shown. An ammeter a is placed in series to measure current. Notice that these shunt resistor values are very low. Get 1 1 help now from expert physics tutors.

If you do not have an ammeter to take readings either do not draw a graph or change the graph to a bar graph which has bright brighter brightest as the values on the y axis. Electricians frequently use these devices to check the faults of the circuits in the building. All of the current in this circuit flows through the meter. In the year 1884 friedrich drexler has invented the first ammeter like moving iron meter.

You have learnt about many of these already. Construct circuits to measure the emf and the terminal potential difference for a battery. Which of the following circuits has the voltmeter and the ammeter placed correctly. An ammeter measures current and a voltmeter measures a potential difference.

Electric circuits can be series or parallel. 5 00005 mω is 5 00005 milli ohms or 0 00500005 ohms.
