Internal Resistance
- Electric Current
- When a switch is closed in a
circuit, free electrons in the
conductor experience an
electric field which causes
them to move in one direction.
- Electrons will
flow from the
negative terminal
of a battery to the
positive terminal.
- Energy is
provided by a
chemical
reaction in the
battery or by
the mains
power supply to
allow the
electron current
to flow.
- When a switch is closed in a
circuit, free electrons in the
conductor experience an
electric field which causes
them to move in one direction.
- Electric Power
- P = IV
- Where I is the current through a
component and V is the potential
difference across a component.
- P = IV
- Resistive Heating
- Electromotive Force
(e.m.f.)
- Resistors in series
- Resistors in parallel
- Internal resistance
- Open Circuit
