⚡️Electric field created by charges on the battery and wires accelerates electrons
🚀Electrons don't carry energy from the battery to the bulb
🌐Electric field extends everywhere throughout the circuit
🔁Electrons are guided by the electric field, not by other electrons
💡Bulb emits light when the electric field reaches it
Do electrons carry energy from the battery to the bulb?
—No, electrons are accelerated by the electric field and dissipate their energy in collisions with the lattice
How does current flow in a circuit?
—Current flows when the electric field created by surface charges accelerates electrons
What is the role of the battery in a circuit?
—The battery creates a potential difference, which establishes the electric field in the circuit
How does the electric field travel in a circuit?
—When a circuit is closed, the electric field propagates at the speed of light, allowing current to flow instantly
Is it possible for information to travel faster than the speed of light in a circuit?
—No, the electric field travels at the speed of light, but it doesn't carry information about the state of the circuit beyond its immediate vicinity
