What else can I help you with?
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
What is the ability to regulate the amount of charge flowing in a circuit?
Resistance
What is the relationship between the voltage output at the interface and the voltage across the series and parallel circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
Total amperage in a series circuit?
Voltage divided by total resistance will give the current. The resistance is simply the sum of all the individual resistances.
If you have a circuit consisting of a battery and a wire What two factors determine the amount of current in the circuit?
The voltage of the battery, and the resistance of the circuit (including the resistance of the wire and the internal resistance of the battery).
What three factors determine the amount of resistance of a material?
In solids, the resistance varies directly as the length of the object and inversely as the cross-sectional ares of the object and coefficient of resistance of the material which is an inherent property that each solid (metal or other) has.
What is the purposed of resistance in the circuit?
Resistance is generally used to control the flow of amount of current in the circuit.
What 3 factors determine the amount of friction in a car?
Wind Resistance, Road Surface, Tire Structure
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
As the resistance in a series circuit is decreased the amount of current in the circuit increases or decreases?
Increases the total resistance
What is the ability to regulate the amount of charge flowing in a circuit is called?
Resistance is the ability to regulate the amount of charge flowing in a circuit.
What is the ability to regulate the amount of charge flowing in a circuit is?
resistance
What is the ability to regulate the amount of charge flowing in a circuit?
Resistance
What components are placed in an electrical circuit to control the amount of resistance in circuit?
resistors, variable potentiometers
When you add resistors that are in a series to a ciruit?
You raise the total resistance by that amount if added in series to a circuit. If you add them in parallel to a circuit then that total resistance will be less than the total of the added circuit.
What is a device that can control the current in a circuit?
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
