Electric circuits and current
What does the these following symbols represent?
A V R
A - Ampere(Amps)
V - Voltage(Volts)
R - Resistance
Where are the electrons before running the battery?
Electrons are everywhere in the battery before turning.
What comparison does voltage make?
A voltage always makes a comparison of the energy at two different points.
When you change the battery voltage, which quantity will change - current, resistance of the bulb or both?
They both change since you're changing the battery voltage.
What is a potential difference?
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.
What does ammeter and voltmeter measure?
Ammeter measures current flowing in the circuit.
Voltmeter measures voltage in the circuit.
What happens when the electrons travel through a bulb?
When electrons travel through a bulb the amount of electrons at higher potential energy enter the lightbulb and give off that energy as they pass through the bulb.
In a plinko what is the current if the height is low and high?
In a plinko, if the height is low the current will be lower. If the height is higher the current will be higher.
What is a voltage rise and voltage drop?
Voltage rise is the difference between two different voltages. A voltage drop is the amount the voltage lowers when crossing a component from the negative side to the positive side.
What is a circuit comparison?
Circuit comparison is the difference between series and parallel circuits.
In a circuit which way does the current always flow from?
The current always flows from positive terminal to negative terminal through the battery.
What happens when you burn steel wool?
The steel wool gets on fire and energy is being transferred to steel wool through electrons.
What is a voltage graph?
A voltage graph represents the energy transfers that take place along one loop of a circuit.
Which elements can we change to observe the current flowing through a bulb?
We can change two elements in a circuit to observe the current flowing through a bulb. We can measure the voltage and the resistance.
What is Circuit connections?
Circuit Connections represents a circuit that has a series and parallel connection. They have their own paths to follow in their connection.
what is a short circuit?
A short circuit is a closed circuit with a source that does not include a load.
What are the four basic elements in a circuit?
The four basic elements in a circuit are - Battery, Wire, Bulb and a Switch.
How does changing the voltage affect the current when the resistance is constant?
Higher voltage = Higher current.
Lower voltage = Lower current.
What is a slope?
The slope is the ratio of the amount that y increases as x increases some amount.
What is a junction point?
Junction point is a point in a circuit where electron current splits up or electron currents join back together.
How do you find if a circuit is open or closed?
In Open Circuit, the electric current charged particles do not flow from an active energy source to the connected load or other components due to the incomplete path. In a closed circuit, the electric current charged particles flow from an active energy source to the connected load or other components due to the closed loop path.
What role does a battery play in a circuit?
The role of a battery in an electric circuit is to supply energy to the circuit by doing work upon the charge to move it from the low energy terminal to the high energy terminal.
How does the resistance affect the current when the voltage remains constant?
The current is directly proportional to the voltage and inversely proportional to the resistance. This means that increasing the voltage will cause the current to increase, while increasing the resistance will cause the current to decrease.
What is a slope of line best fit?
The line's slope equals the difference between points y coordinates divided by the difference between their x coordinates.
How do you find if a circuit is series or parallel?
In a series circuit all components are connected to form a single path for electrons to flow. In a parallel circuit all components are connected across each other forming two sets of division for electrical common points.
