Current Electricity Review Flashcards
In your own words explain what static electricity current is? What is the symbol and units for current?
Electric current is the flow of electricity. The symbol is I and the unit is amperes(A).
Explain what electric potential difference is? What is the symbol and units for current?
electric potential difference is the amount of energy the electrons are carrying between 2 points. The symbol is V and unit is volts(v)
What is resistance? What is the symbol and units for current?
Resistance is the ability of a material to oppose the flow of electrons through it. The symbol is RR and the unit is Ohms (-0-)
State the characteristics of a series circuit and a parallel circuit in terms of ythe electric current and voltage across each load.
In a series circuit the current stays the same throughout and in parellel circuit it splits among the branches. In a series circuit the voltage splits amoung the loads and in a parallel circuit all loads hav the same voltage as the battery or cell.
What happens when one bulb burns out in a circuit made up of six bulbs connected in series with one another?
All the other bulbs would stop lighting up because the electrons cant flow through the bulb that burnt out.
Why are series circuits with more than three loads not very common?
they are not very common because the light bulbs get dimmer, the more you add.
What is current electricity?
steady flow of electrons
What is current?
Is the measure of the rate at which the electron flow in a circuit
What is voltage?
Amount of energy the electrons are carrying as the flow between two points
What is resistance?
the ability of a material to oppose the flow of electrons through it - restricting the flow of electrons
What batteries or cells
sources that store chemical energy and transfer it to electrical energy when a circuit is connected
What is a parallel circuit?
Parallel connections provide multiple/two pathways for electrons to travel
What is a series circuit?
Series connections provide only a single pathway for electrons to travel.
