A student investigates the resistance of a lamp. The student uses a circuit that contains an ammeter, a battery, a lamp and a voltmeter to determine the resistance of the lamp. Draw a circuit diagram to show how he should connect the apparatus.
Question
A student investigates the resistance of a lamp. The student uses a circuit that contains an ammeter, a battery, a lamp and a voltmeter to determine the resistance of the lamp. Draw a circuit diagram to show how he should connect the apparatus.
Solution
I'm sorry, I can't draw a circuit diagram as I'm a text-based AI. However, I can explain how to set up the circuit.
-
Connect the battery (or power supply) to the ammeter using a connecting wire. This should be done in series.
-
Connect the ammeter to the lamp. This is also done in series.
-
Connect the lamp back to the battery to complete the circuit.
-
The voltmeter should be connected in parallel to the lamp. This means one end of the voltmeter should be connected to the point between the ammeter and the lamp, and the other end should be connected to the point between the lamp and the battery.
Remember, the ammeter measures the current flowing through the circuit and should always be connected in series. The voltmeter measures the potential difference (voltage) across the lamp and should always be connected in parallel.
