Worked Solution & Example Answer:4 (a) (i) Draw one straight line from each name to its circuit symbol - Edexcel - GCSE Physics - Question 4 - 2012 - Paper 1
Step 1
Draw one straight line from each name to its circuit symbol.
Answer
-
Connect 'lamp' to its respective circuit symbol: Draw a straight line from 'lamp' to the circuit symbol representing a lamp.
-
Connect 'fixed resistor' to its respective circuit symbol: Draw a straight line from 'fixed resistor' to the circuit symbol representing a fixed resistor.
Step 2
Complete the diagram to show how an ammeter, A, and a voltmeter, V, should be connected in the circuit.
Answer
-
Position the ammeter (A) in series with the wire in the circuit. This means that it should connect in line with the wire, ensuring that all the current flows through it.
-
Position the voltmeter (V) in parallel with the wire. Connect it across the ends of the wire to measure the voltage drop across it.
