CLIV ever Sch 1. The voltage rating as stamped on the battery is called the batteries Emf. This is the battery's "full" potential before any current is drawn. However once the battery starts to operate it deli less than this rated Emf value. Its "operating voltage" is known as the terminal voltage, V. Suggest why Vr < Emf: 2. Ensure that the sim is set to view the flow of electrons. What do you notice about the flow when all of the switches are left open? 3. Click on the voltmeter (right side) and drag it to the circuit. Read the voltage across your battery (place wire leads of meter on either side of the battery) with the switch on the left open and record the value. If you get a negative voltage simply swap the leads or ignore. Is this value the battery's Emf or terminal voltage, Vr? How do you know? Voltage across the battery when switches open = Emfor terminal voltage, Vr? Explain above choice: 4 . Close the switch on the left and note that the current starts to flow. What is the voltage across the battery now? Why do you think it changed? Voltage across the battery when left switch closed = Emf or terminal voltage, Vr? Explain above choice. Why has the reading changed when even though the voltmeter is connected to the same points
