Question

Draw the labelled diagram of an electric circuit comprising of a cell, a resistance, an ammeter, a voltmeter and a closed switch (or closed plug key). Which of the two has a large resistance : an ammeter or a voltmeter?

Answer 1

Here is the diagram of an electric circuit comprising a cell, a resistance, an ammeter, a voltmeter and a closed switch 

 

 

A voltmeter has a high resistance so that it takes only a negligible amount of current from the circuit.
