Term
 What is the colour range for 0-9?
Definition
 Black - 0Brown - 1Red - 2Orange - 3Yellow - 4Green - 5Blue -6Purple - 7Grey - 8White -9
Term
 How to get resistance from colour number values?
Definition
 a,b,c(a0+b) x [10(to the power of c)]eg)3,2,230+2 x 10(sqaured)32x1003.2x10003.2k3k2 (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=1000M= 1,000,000
Term
 Resistors
Definition
 Are materials that restrict the flow of current.
Term
 Resistors
Definition
 Are materials that restrict the flow of current.
Term
 Ohmic resistors
Definition
 Have a linear relationship when comparing voltage to current
Term
 Series circuit
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...
Term
 Total resistance in series circuits
Definition
 Rt = R1+R2...
Term
 Ohms laws!
Definition
 V=IRI=V/RR=V/I
Term
 As total resistance increases, the current ...
Definition
 Decreases
Term
 I= T,Q
Definition
 I = Q/T
Term
 V= Q,E
Definition
 V= E/Q
Term
 P= e,t
Definition
 P= E/T
Term
 I(Squared)R = V, R
Definition
 = V(squared)/r
Term
 E
Definition
 Energy
Term
 Q
Definition
 Chargeno. of electrons
Term
 A parallel circuit contains
Definition
 More than one loop
Term
 Current in parallel circuit
Definition
 Is shared between loops:It = I1+I2+I3...
Term
 Voltage is parallel circuits
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 ORR1xR2/R1+R2...
Term
 In parallel circuits, elements or resistors are
Definition
 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 increasesMore voltage consumedMore resistance!
Term
 Resistors
Definition

Term
 More resistors in series circuit means
Definition
 Higher resistance'Higher voltageLess current
