Series and Parallel Circuits

Question 1

what happens in a series circuit

Answer 1

two or more electrical components are connected one after another on the same conducting pathway.

a break in any part of the circuit disables all components in the circuit

Question 2

current and voltage in a series circuit

Answer 2

current is same ( I = I1 = I2 = I3 ….)
voltage is different ( V = V1 + V2 + V3

Question 3

equivalent resistance in series circuit

Answer 3

R = R1 + R2 + R3….

Question 4

what happens in parralel circuits

Answer 4

two or more electrical components are connected on different conducting pathways

a break in conducting pathway will still allow charge to flow through any other pathway

Question 5

example of series and parralel circuit

Answer 5

series: torch
parallel: household lights

Question 6

voltage and current in a parallel

Answer 6

voltage is the same (V = V1 = V2..)
current is different (I = I1 + I2 + I3…)

Question 7

equivalent resistance in parralel circuits

Answer 7

R = 1/R1 + 1/R2 + …
