Hello, I am studying for a large test that I have this week and I came across a question that I don't know the answer to. Please can someone help. Here is the question:
3. An ammeter is connected in. The circuit in series to the battery. The variable resistor is then adjusted until the ammeter reading is 2.0A. The voltmeter reading is then 9.0V.
b. Calculate the energy transferred to or from each coulomb of charge when it passes through each component including the battery. (3 Marks)
Thank you in advance! 😊

Use the equation E = VIt ( Energy = Voltage * Current * time).
You can calculate the time using Q = It where Q is the constant charge of an electron.
Hope this helps!
