Science Project _ Electric Circuits- factors affecting voltage,amperage, resistance.
In a closed electric circuit, resistance of the components and the voltage of a power source
are affecting the electric current. Current is the rate of flow of electrons.
What are the 3 effects of current flowing in a conductor?
When current flows in a circuit it exhibits various effects. The main effects are
heating, chemical and magnetic effects
.
What are the factors that affect the flow of current?
Resistance
opposes current and therefore the higher the resistance, the smaller the current. Therefore the factors that affect the resistance are the same factors that control the flow of current through a wire. In the above diagram the circle represent the ions and the red line represents the flow of electrons.
What are the 3 factors that define a circuit?
A circuit is the path that an electric current travels on, and a simple circuit contains three components necessary to have a functioning electric circuit, namely,
a source of voltage, a conductive path, and a resistor
.
What are the two factors that affect the current in a circuit?
IN a simple circuit
supply voltage and Resistance
determines the current.
What are 5 factors that affect current flow?
There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors
(temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors
(atmospheric pressure, winds, rainfall, evaporation and insolation); factors that …
What are the 3 factors that affect resistance?
Factors That Affect Resistance
How much resistance a material has depends on several factors:
the type of material, its width, its length, and its temperature
. All materials have some resistance, but certain materials resist the flow of electric current more or less than other materials do.
What are the different effects of current?
- Magnetic effect.
- Chemical effect.
- Heating effect.
- Electric shocks.
Does length of wire affect current?
Current flow will decrease
. Wire has resistance. The longer the wire, the higher the resistance, the less current will flow.
How does current flow in a conductor?
Current is
flow of electrons
, but current and electron flow in the opposite direction. Current flows from positive to negative and electron flows from negative to positive. Current is determined by the number of electrons passing through a cross-section of a conductor in one second.
What is circuit explain?
A circuit is
a closed loop that electrons can travel in
. A source of electricity, such as a battery, provides electrical energy in the circuit. Unless the circuit is complete, that is, making a full circle back to the electrical source, no electrons will move.
What makes up a circuit?
Circuits are made up of two distinct elements:
active elements
, which are defined as the sources of electrical energy, and passive elements, which carry or use the electrical energy for some specific reason.
What are the factors affecting the resistance?
Resistance is the property of the material that restricts the flow of electrons. There are four factors affecting resistance which are
Temperature, Length of wire, Area of the cross-section of the wire, and nature of the material
.
What are the 5 factors affecting resistance?
length – longer wires
have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance.
What are 4 factors that affect resistance in a circuit?
- The type of material of which the resistor is made.
- The length of the resistor.
- The thickness of the resistor.
- The temperature of the conductor.
What two factors does current depend on and what are their units?
The amount of current in a circuit depends on
the amount of voltage and the amount of resistance in the circuit to oppose current flow
. Just like voltage, resistance is a quantity relative between two points.
