90% OF STUDENTS WILL GET THIS WRONG!
A battery has:, EMF = 24 V
Internal resistance = 4 Ω
External resistor = 32 Ω
👉 QUESTION:
What is the TERMINAL p.d of the battery?
Most students rush and shout 24 V❌
But JAMB LOVES this trap .
If you don’t understand internal resistance, this one will humble you in the exam.
JAMB has repeated this concept for YEARS.

PHYSICS IS COOKING… LITERALLY!🔥🔥 🔥
That pot of soup on your gas burner isn’t just food . It’s a full physics laboratory in action 👇
Heat Transfer at Work.
The blue flame releases energy through COMBUSTION transferring heat to the metal pot by CONDUCTION.
CONVECTION CURRENT:
Hot soup at the bottom becomes less dense and rises, while cooler soup sinks.
That beautiful swirling motion? 👉 natural convection keeping your soup evenly cooked.
EVAPORATION & BOILING:
The steam you see escaping isn’t smoke, it’s water molecules gaining enough energy to escape the liquid phase.
PARTICLE MOTION:
As temperature increases, particles move faster, collide more, and spread energy throughout the soup.
👉 Every time you cook, you’re applying THERMODYNAMICS, KINETIC THEORY and ENERGY TRANSFER without opening a textbook.
Physics isn’t abstract.
Physics is practical.
Physics is delicious 😄

ONLY SMART JAMB STUDENTS WILL GET THIS RIGHT!** 🚨
This projectile motion question** has confused many candidates in past JAMB exams 😳
👉 A shooter fires a bullet such that its horizontal range is three times its maximum height. What angle should he fire the bullet?
Most students choose the wrong angle.
Will you get it right?
