Chapter 5: Sources of Electricity
Primary Cells
Chemical action cannot be reversed; it cannot be recharged.
Secondary Cells
Can be recharged
Voltage in Series
Vtotal = S V
Total voltage or equivalent voltage is the sum of the voltages
Voltage in Parallel (more in the next 2 chapters)
Vtotal = Van individual battery Note: You do not mix
Series Parallel Configuration (more in the next 2 chapters)
Approach is to convert the parallel circuit to a series circuit (procedure covered later) and then perform calculations on the equivalent series circuit
Battery Capacity
Ability to produce a current over a designated period of time.
Typically measured in ampere-hours (Ah)
Electrical Energy from Light
When it warms up we will visit the solar power array on campus.
Material on this topic will be presented at that time.
