A Level Physics worksheet containing questions about the lesson: EMF & Internal Resistance

Model Answers Included

This worksheet covers the following content:
-electromotive force (e.m.f.) of a source such as a cell or a power supply
-energy transferred; W = εQ
-internal resistance
-terminal p.d. and lost volts
-the equations E = I(R + r) and E = V + Ir
-analysis of circuits with more than one source of e.m.f.
-techniques and procedures used to determine the internal resistance of a chemical cell or other source of e.m.f.

This is tailored for the OCR A specification, however, the versatile nature of this resource makes it suitable for other exam boards too.

This resource is designed to help students apply their knowledge to questions. This active revision technique ensures that the worksheet will be very useful for students, and will act as a vital revision tool.
