H1 Physics reflections …

Was tutoring on the topic Current Electricity just now. For this topic, students normally have difficulty in understanding the concept of internal resistance of a cell and terminal potential difference, as these concepts are not covered at the O-Levels. It is important for students to deeply understand the equation E = V + Ir, and its related graph of V against I, as well as the significance of I being zero.

If you are a H1 Physics student, you’d find that many of the topics are quite similar to the O-Level topics; so focus on understanding the new stuff, the A-level stuff, such as F = BILsin(angle), for example, and concepts such as magnetic flux density.
