Simple Electrical Circuits Lesson 2-The Basics Recap Draw the circuit symbol for a bulb Draw the circuit symbol for an ammeter What component is used to measure electrical current? A. Switch B. Resistor C. Ammeter D. Voltmeter Which component changes electrical energy into light energy? A. Bulb B. Switch C. Cell D. Battery Which component is a store of chemical energy? A. Bulb B. Battery C. Switch D. Resistor Which of these materials is not a conductor of electricity? A. Water B. Graphite C. Lead D. Wood Name this circuit symbol. A. Ammeter B. Switch C. Bulb D. Voltmeter V Q1. Is the circuit below a series or parallel Q2. If the reading on Ammeter A is 2AWhat will the reading on A2 and A3 be? A A3 A2 Q1. Is the circuit below a series or parallel Q2. If the reading on Ammeter 4 is 2A what will the reading on: A2, A3 and A1 be? A1 A4 A2 A3 Q1. Is the circuit below a series or parallel Q2. If the reading on Voltmeter 1 is 8V what will the readings on V2 and V3 be? V1 NB Voltmeters are connected in parallel V2 V3 • For a series circuit, the sum of the voltages for each component is equal to the voltage across the cell or battery. • V1 = V2 + V3 Q1. Is the circuit below a series or parallel Q2. If the reading on Voltmeter 1 is 8V what will the readings on V2 and V3 be? V1 V2 V3 • For a parallel circuit, the voltage across the cell/battery is the same as the voltage across each branch. • V1 = V2 = V3
