Energy Transfers And Electrcity Flashcards
What happens with the current in series
Stays same at all points
What has a simple series circuit have
Draw 1
Ohhnburvgffnkhuhsejhewrifvk actually do!!!!!!! You lazy waste man
What about voltage in series circuit
Splits evenly across the components and adds up to the cell voltage
Cell - 6
Bulb 3v
Bulb - 3v
Current in a parallel circuit ?
Splits evenly unless different or faulty bulb
Voltage in parrallel
?
Voltage stays the same across the parrallel parts’
Say out Loud the a question for both circuits to answer

What is the symbol for current
i
What is resistance
Restricts the flow of electrons
What’s resistance measured in
Ohms
What affects the resistance and flow of electrons
A hotter circuitry is quicker (electrons speed)
How do u add up resistance
Add up all the ohms
R1. +. R2. =
3ohms 3ohms. = 6 ohms
Equation for resistance?
V
i. X. R
What’s v
Voltage
What’s i
Current
What is current measured in
Amps
Reminder : write what the symbols are and what measured in when drawing the pyramid for resistance
Lllllllooooollllllll
What changes the amount of resistance
Having a longer, larger and temperature of wire
Energy
Name all the types of energy
Kinetic, nuclear, light, gravitational potential , thermal, elastic, sound, electrical, chemical
What 3 ways is heat transferred by
Conduction, convection, radiation
Talk about b ball thingy

Questions
Light bulb , what’s produced or what’s the products
Electrical to light and heat
What is wasted in the example of the light bulb and useful energy
Light - useful
Heat - wasted
Answer the ones for torch kettle and radio, also giving the useful and wasted types of energy.
Should know
