Previous Knowledge: the students were already thought;
What is a capacitor?
What is capacitance measured in?
What is an application of a capacitor?
How to calculate capacitance in series.
How to calculate capacitance in parallel.
How to draw the equivalent circuit for capacitors in series or parallel.
Introduction of lesson:
Teacher will tell students the objectives of the lesson.
Today we will have our lesson continuing our calculating capacitors.
Recall :
How to calculate capacitance in series.
How to calculate capacitance in parallel.
How to draw the equivalent circuit for capacitors in series or parallel.
We will be putting what we learnt in previous classes into action.

Application:
A hand out will be given to student for them to calculate the total capacitance of the
circuits and draw the equivalent circuits.
1. Series Circuit 1, C1 = 26F and C2 = 18F
2. Series Circuit 2, C1 = 32F and C2 = 96F
3. Parallel Circuit 3, C1 = 38 ,C2 = 80F and C3 = 20F
Continues in the Hand out.
Summary/Student Evaluation
A hand out will be given and students will be ask to calculate the total capacitance
of the circuits in their books, and also draw the equivalent circuit.
Then the teacher will project the questions on the white board and ask student s to
give him the answers.
