1
Q

what happens in a series circuit

A

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

2
Q

current and voltage in a series circuit

A

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

3
Q

equivalent resistance in series circuit

A

R = R1 + R2 + R3….

4
Q

what happens in parralel circuits

A

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

5
Q

example of series and parralel circuit

A

series: torch
parallel: household lights

6
Q

voltage and current in a parallel

A

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

7
Q

equivalent resistance in parralel circuits

A

R = 1/R1 + 1/R2 + …
