Electricity
Current
Is a flow of charged particles.
Conductors let current flow.
Measured in amps(amperes).
Insulators stop current from flowing.
Charges
Negative
Like (same) charges repel
Positive
unlike (different) charges attract
Ohm's law
Resistance= R
V=IR
V= Volts
Current= I
Static
Charges can't move so charge Builds up
Charges move when circuit completed shocks, sparks.
Electrons rubbed from one thing to another
Circuits
Series
More batteries added: Brighter bulbs but more energy used
Voltage is shared
Current is the same everywhere.
If one bulb goes out the others also.
Parallel
More batteries added: same brightness of bulbs and saves more energy.
Current is shared.
Voltage is the same for all branches.
if one bulb goes out the others stay On.
Resistance
Makes if hard for particles to move.
the more resistance the smaller the current.
