Question
I am not sure where to label z please complete answer a and b
(a) The diagram shows the circuit used to investigate how the current varies with potential difference for an electrical component P. The circuit contains an ammeter and a voltmeter. (i) On the diagram, label the V. aceross Ammeter conn ecteel in sertes' to the cirLuil. (ii) The position of the contact of the potential divider is moved so that the reading on the voltmeter becomes zero. Label this position Z.
