Practical Circuits 6.3 Flashcards
What is Current in Series Circuit?
-Have all their components placed one after the other in a single loop
-Only one path for electrons to flow
-Current flowing is the same
-If energy user broken, entire circuit breaks
What is Voltage in Series Circuit?
-Voltage supplied by battery is shared by all components in circuit
-The more components the less each receives
What is Resistance in Series Circuit?
-Resistance of each component adds up to give total resistance
-More components = more resistance
What is Current in Parallel circuit?
-Parallel circuits can have multiple paths or branches containing components
-Each branch draws current PROPORTIONAL to its resistance
-Total current found by adding the current by each branch together
What is Voltage in Parallel Circuit?
-Each branch gets FULL voltage of the battery, components don’t need to share
-All light bulbs have maximum brightness
-Each branch can have its own switch which can be turned on/off independently
What is Resistance in Parallel Circuit?
-Do not add the resistance of different branches together
-Have less resistance overall as there are multiple paths for electrons to flow, higher current
What are Combination Circuits?
-Made of components in both series and parallel
What is Household Wiring?
-Large parallel or combination circuit
-Each branch receives full 240V
-Each branch can be controlled by independent switches
-Fault in one branch does not affect other branches
What are Electrical cables made of?
-Three separate wires:
*Active: Brown
*Neutral: Blue
*Earth: Green and Yellow
-Active brings electricity in
-Neutral takes current out
-Earth prevents ELECTROCUTION
What are the Electrical Safety?
-Have devices to prevent excessive current flow
-Reduce chance of house fire and electrocution
*1.Fuses: Devices with wires melt at high temperature, breaking the circuit
*2.Safety Switches: Prevent electrocution in people, detects leaking current in 0.03 seconds
*3.Circuit Breakers: Protect wiring and circuitary, prevent appliances from overheating, reduces risk of fire.
