5.4 Electrical currents and energy transfer

Question 1

Charge flow calc =

Answer 1

I x T

Question 2

What energy transfer happens when electrical charge flows through a resistor

Answer 2

From chemical energy store in battery to resistors store of thermal energy

Question 3

What happens when a resistor is connected to a battery

Answer 3

work is done, electrons pass through the resistor, electrons collide with vibrating metal ions, transferring energy. Gain kinetic energy, vibrate more. Causing resistor to get hotter.
