Cells in Series and Parrallel

Question 1

Cells are connect in series if?

Answer 1

• the positive pole of one cell is connected to the negative pole of another cell
• there is only one path for the current

Question 2

Cells are connected in parallel if

Answer 2

• the positive pol of each cell is connected to the positive pole of the next cell
• there are as many paths for the current as there are cells

Question 3

Tell the effects on the brightness of the lamps if…
Scenario:
1) one cell; one lamp
1) two cells in series; one lamp in series
1) two cells in parrallel; one lamp in series

Answer 3

• the lamp of the circuit with one cell is about as bright as the lamp with two cells connected in parallel
• the lamp in the circuit with two cells in series is much brighter

Question 4

What is meant by series?

Answer 4

a circuit where the current passes through the components one after another

Question 5

What is meant by parallel?

Answer 5

a circuit that has more than one path for the current

Question 6

Tell the effects on the brightness of the lamps if…
Scenario:
1) a circuit, one cell; a switch and one lamp
2) a circuit, one cell; a switch and two lamps in series
3) a circuit, one cell; a switch and two lamps in parrallel

Answer 6

• the lamp in the circuit with one cell is about as bright as the lamps in the circuit with two lamps in parallel
• the lamps in the circuit with two lamps in series are the dullest
