The SPM Physics Workbook is developed under the One-School.net Free Books Project. The content of this book is strictly follow Malaysia SPM (Sijil Pelajaran Malaysia) syllabus. The aim of this project is to provide a complete electronic supplementary network for students to develop self-learning skills by breaking the spoon-feed rituals and to encourage them to compile educational information from the Internet.

1) Referring to the figure above, find the reading of the voltmeter V2.

 12V 5V 7V 19V

2) Referring to the figure above. If the reading of the volmeter V1 is 5V, what is the reading of the ammeter V2?

 5V 4V 3V 3.3V

3) Which of the statements below about the circuit above is true? (Assume that the cells have no internal resistance.)
 The reading of the voltmeter is equal to 12V. The reading of the voltmeter is less than 12V. The reading of the voltmeter is higher than 12V.
