Introduction
Good morning Learners.
In this lesson of today we will be focusing on electric circuits which is our last chapter on the physics part next week we will be covering the chemistry part. This topic of electric circuits runs for 8 hours meaning we need to pay more attention and use our time correctly. The prior knowledge from previous grades grade 7-9 Qualitative aspects: Static electricity, The magnetic effect of electric current (electromagnets), Forces and force fields (gravitational, magnetic and electric fields). Here in Grade 10 by the end of this lesson you should be able to : • Define the Emf and terminal potential difference, and Current
• Measurement of current and potential difference
• Define the term resistance in electric circuits
• Calculate the resistors in series
• Calculate the resistors in parallel
Electric circuits count about 18% in the final examination. Electrical appliances, cell phones, cars, household lighting and industry all run on electricity. It is therefore important to know and understand the basic principles of electric circuits, and to work with circuits safely. This topic deals with DC (direct current) battery powered circuits. The voltages and currents cannot harm the learners when they experiment with circuits. Click the link below and do the follow up questions base on the link.
