1. Make a Venn Diagram comparing emf of a source and potential difference across the circuit. 2. The battery supplies a maximum voltage of 12 V. When it is connected to an external circuit, the voltage measured by the voltmeter across the circuit is only 10 V. Is this possible? Explain your answer. 3. Why do the problems occur when an ammeter is connected in parallel with the lamp?
