Term
Series circuit
Definition
A circuit that only has one pathway for electrons to flow
Term
Current for series circuit
Definition
It is the same throughout
Term
Voltage in a series circuit
Definition
The voltages at each load with add up to the voltage supplied
Term
Resistance in series circuit
Definition
The resistance will go up if a resistor is added and the current will slow down
Term
Parallel circuit
Definition
A circuit that has more than one pathway for electrons to flow
Term
Voltage in parallel circuit
Definition
The parallel loads are equal to each other
Term
Current in a parallel circuit
Definition
The current in equals the current out
Term
Resistance in a parallel circuit
Definition
The resistance decreases because there is more pathways so there is more ways for the electrons to flow and the current will increase
Term
Power
Definition
The rate at which work is done or energy is transformed; unit used is watt
Term
Power rating
Definition
A measurement of how much electrical energy an electrical device costumes for every second it is in use
Term
Two ways to calculate energy consumption
Definition
E=Pt
: E= (Watt)(Second)
or
E=Pt
E= (Kilowatt)(Hour)
Term
How to determine price of electricity bill
Definition
Multiply the energy consumption, it has to be in kilowatt hours, and multiply it by the price
