Electricity Flashcards
What is the current at every point in a series circuit?
In a series circuit the current is the same at any point.
What does the current in each of a parallel circuit’s sum to?
In a parallel circuit, the current in the branches sums to the total current provided by the power supply.
What does electricity always do relative to resistance?
In always flows in the path of the least resistance.
How is voltage distributed in a series circuit?
The voltage divides equally among the number of devices.
How is the voltage distributed in a parallel circuit?
Each branch receives the voltage of the power supply.
What does combining the resistance in a series circuit do?
It increases the resistance.
What does combing resistances in parallel do?
It decreases the resistance.
What is the formula for Power?
P = V x I where P = power, V = voltage and I = amperage
What is the unit of current?
An ampere.
What is the unit of charge?
A coulomb.
What does 1 coulomb/second equal?
1Amp.
What is another name for voltage?
Joules/coulomb.
What is voltage a measure of?
Potential difference.
What are materials that prevent the flow of electric charge called?
Non-conductors or insulators.
What form will carbon conduct electricity in?
Graphene.
