Electricity
Factors
Voltage (Volts)
Potential difference, the energy to move charges
Measured by a Voltmeter in parallel
"Water pressure in a hose"
Resistance (Ohms)
Opposes current flow
"Friction of water"
Controlled by fixed and variable resistors
Affects current
Current (Amperes)
Rate of flow of charges
"Speed of water that flows from a hose"
Measured by an Ammeter in series
Circuit formation
Series
More bulbs / resistors in series
effective resistance increases
Bulbs become dimmer
Parallel
More bulbs / resistors in parallel
effective resistance decreases
Bulbs become brighter
Power
kWh ( xthousands watts per hour)
Watts x 1000 x (60 minutes ÷ time) = kWh
