Topic 2 - Technologies can be used to transfer and control electrical energy

Perfect conductors: not resistance to electron flow.

Allows electrons to pass.

Measure of how difficult it is for electrons to flow through a substance.

Ohms

Resistor whose substance was modified or changed by adjusting portion of resistor current travels through.

V = I x R I = V/R Ω = V/I

Meters utilized to measure small voltages.

Used to measure electrical current in amperes.

Meters used to measure small currents.

Used to measure voltage, current, resistance.
