Grade 9 November Exams > Physics- Cells Connected In Parallel > Flashcards
To connect two or more cells in parallel
Positive poles of the cells must be connected together and the negative poles must be connected together
Cells can only be connected in parallel
If their voltages are the same
Voltage of cells connected in parallel
Is the same as the voltage of an individual cell
1/Rtotal =
1/R + 1/R= 2/R
Rtotal= R/2
1/Ref =
1/R1 + 1/R2= 2/R
Ref= R/2
Ref= 1,… ohms
Current is divided by
Parallel resistors
Current dividers
