Karteikarten: Fundamentals of Heat and Electricity — 14 Karten

Heat transfer methods — types?

Conduction, convection, radiation.

Conduction — mechanism?

Heat transfer through direct contact.

Convection — mechanism?

Heat transfer via fluid movement.

Radiation — mechanism?

Heat transfer via electromagnetic waves.

Surface heat absorption — dark surfaces?

Absorb more radiation, heat faster.

Surface heat reflection — light surfaces?

Reflect more radiation, stay cooler.

Electrical circuit — main component?

Power source (battery) drives current.

Conductors — example?

Copper, aluminium, metals.

Insulators — example?

Plastic, wool, cotton.

Electricity types — main?

Static and current electricity.

Current — definition?

Flow of electrons in a circuit.

Voltage — role?

Pushes electrons through the circuit.

Resistors — effect?

Limit or oppose current flow.

Real-world heat example — metal spoon?

Heat transfer via conduction from hot coffee.
