Definition
Black  0 Brown  1 Red  2 Orange  3 Yellow  4 Green  5 Blue 6 Purple  7 Grey  8 White 9 


Term
How to get resistance from colour number values? 

Definition
a,b,c
(a0+b) x [10(to the power of c)]
eg)
3,2,2 30+2 x 10(sqaured) 32x100 3.2x1000 3.2k 3k2 (ohms) 


Term
How do you neaten up resitor vlaues 

Definition
Try to get them to K or M and then put decimals on the other side of the letter!
K=1000 M= 1,000,000

Term

Definition
Are materials that restrict the flow of current. 


Term

Definition
Have a linear relationship when comparing voltage to current 


Term

Definition
Has only one loop in which all elements are placed into. 


Term
Current in a series circuit 

Definition
Will be the same through all elements and the whole loop 


Term
Voltage in a series circuit 

Definition
Is supplied by the power source and is shared between the resistors.
Vt = V1 + V2...

Definition
Is the same through each loop! 


Term
Total resistance (effective resistance) in parallel circuits is 

Definition
1/RT = 1/R1 + 1/R2 + 1/R3
OR
R1xR2/R1+R2... 


Term
In parallel circuits, elements or resistors are

Independent! eg) globes won't blow out if one does 


Term
As more loops are added in a parallel circuit, the power consumption, resistance and voltage... 

Definition
Power consumption increases More voltage consumed More resistance! 


Term

Definition

Term
More resistors in series circuit means 

Definition
Higher resistance' Higher voltage Less current
