💡Physics with Heera

📡Chapter 3 : Electricity

! IMPORTANT DEFINITIONS !
Part 1

🔎E.H.T
👉🏻Extra high tension

🔍Electric field
👉🏻The REGION around a charged particle where any charge in the region will experience an electric force.

🔍Electric field strength, E
👉🏻Electric force acting on a unit postive charge placed at a point.

🔍Current, I
👉🏻The rate of flow of charge, Q in a conductor

🔍Potential difference, V
👉🏻The work done, W in moving one coulumb of charge, Q from one point to another.
V = W/Q or
V = E/Q

🔍Resistance
👉🏻Ratio between potential difference, V and current, I.
R = V/I

🔍Rheostat
👉🏻Control the current flow

🔍s.w.g.
👉🏻Size wire gauge

! IMPORTANT DEFINITIONS !
Part 2

🔍Resistivity of a conductor, p
👉🏻Measure of a conductor's ability to oppose the flow of the electric current.

🔍Superconductors
👉🏻Materials that conduct electricity without any resistance.

🔍Critical temperature, Tc
The temperature when the resistivity of a superconductor becomes ZERO.

🔍Electromotive force (e.m.f.)
Energy transferred or work done by an electrical source to move one coulumb of charge in a complete circuit.

🔍Voltage drop
Value of potential difference across the circuit, V is SMALLER than the e.m.f. of the dry cell
V < e.m.f.

🔍Internal resistance, r of dry cell
The resistance caused by electrolytes in the dry cell
🧠Apa effects??
😿Loss of energy in the form of heat in dry cell
😿V < e.m.f. ---- (voltage drop👀)

Look at this ! 🌵

What do you suggest min buat dgn pokok ni 🤔

Btw, I have a LOT OF CACTUS plants just sitting in my house🥲 geng2 Kuantan ada yang nak pokok cactus tak? 😙
Min nak get rid of some tbh 😂

Cactus are succulents 🌵 so bila min break the cactus apart, boleh nampak air keluar🥹

#biology

Don't worry, I'm not torturing the plant 😂 it's dying anyways, might as well use it to show you guys how cactus are succulent plants

Assalamualaikum dan selamat pagi semua.

Cikgu masih kepenatan memandu sejaub hampir 500km dari Raub ke Kuala Terengganu. Harap dapat kembali bertenaga selepas sarapan nanti.

Cikgu terima video ini melalui aplikasi Whatsapp. Sangat menyedihkan hati. Saat bilangan Harimau Malaya yang semakin berkurang dan diancam kepupusan, mereka temui bangkai harimau malang di dalam sungai di Dabong, Kelantan.
Siasatan masih dilakukan untuk mengetahui punca kematian harimau ini.

Boleh tak senaraikan ancaman² terhadap haiwan² seperti Panthera tigris jacksoni yang boleh menyebabkan kepupusannya dan bagaimanakah langkah untuk menanganinya.

Assalamualaikum and Hallooo🙈❤️

Okey so min nak cerita2 ahh sikit

Lama dah en tak bercerita nii😂hahahah

This morning I was in charge of helping the teachers register the new form 6 students ahh😝🔥 which means min duduk ahh dkt meja pendaftaran haha

Anyways, when I first met the new juniors, adalah first impression towards them 🫢 bolehla nampak/agak2 siapa budak2 yg akan skor STPM nnti InshaAllah 🫡
Not only that, cara mereka bawa diri mereka and their efficiency in doing their work reflected their personalities 😲
Some kind of students I met includes Charismatic ones 😎, humble ones🥹, shy2 cat (kurang bercakap)🤫, the kelam kabut one😂 and many more 😋

Another thing people don't mention always is that kita boleh agak what kind of student someone is by the way they, STAND, WALK and TALK 😹👏

So yeah, wherever you go, pastikan bawak diri as well as you can🙂‍↕️ first impression matters ya✌️🏻

By they way, kepada yang belum tahu🙈
Min sebenarnya sambung belajar taking STPM 2024 😜🙌🏻 ambik aliran sains hayat (Biology + Chemistry + Maths Technical) 🫡
So yeah that'll explain why I'm involved in pendaftaran pelajar baru form 6🤓

Anyways, tolong doakan semoga min mencapai 4 Flat in Semester 2 STPM 2024 🥹🤲🏻 aamiinn
Terima kasihh adik2 semua, semoga doa ini berbalik kepada adik2 semua yg menduduki peperiksaan SPM 😚

Assalamualaikum gaissss

Siapa nak kak heera buat class chemistry ? Hehe
