Rules for series + parallel circuits

Question 1

In a series circuit, what can we say about the current?

Answer 1

• in a series circuit, current is the same everywhere

Question 2

In a parallel circuit, what can we say about the voltage?

Answer 2

• in a parallel circuit the voltage is the same, across all components

Question 3

In a parallel circuit, what can we say about the current?

Answer 3

• in a parallel circuit, current is shared between branches

Question 4

In a series circuit, what can we say about the total resistance?

Answer 4

• in a series circuit, resistance is the Sum/total of resistance [because by adding a resistor in series, those two resistors have to share the voltage]

Question 5

In a series circuit, what can we say about the voltage?

Answer 5

• in a series circui, the voltage is shared [and is equal to the total voltage across the cell]

Question 6

In a parallel circuit, what can we say about the total resistance?

Answer 6

• in a parallel circuit, the total resistance is lsss than the individual resistance [of the smallest resitor]
