Compare and contrast the flow of the water in a pipe and the flow of electrons in a wire?
The bigger the pipe the less resistance to water flow which is analogous to the electrons in current flow. As you make the pipe narrower the resistance to water flow would increase (Less water would flow). Hence higher resistance means lower current in both water and electrical example.
If you had a big vat filled with water and a spigot at the bottom you could turn on and off, you could simulate voltage and current.
The water in the vat represents the potential voltage or stored electron charge. With the spigot off the voltage is constant and the current (flow) is zero. If you open the spigot a small amount you get a trickle of water flowing since the resistance is very high. This will make the water (potential) last longer like a battery that has a small load. As the spigot is opened more, more current flows and the quicker the potential will be reduced to zero.
What else can I help you with?
How did the voltage produced by the two metals in water compare to when the metals were in the fruit e?
The voltage produced by the two metals in water is typically lower than when they are placed in fruit. This is because the acidic or electrolyte properties of the fruit enhance the electrochemical reaction between the metals, allowing for a more efficient flow of electrons. In contrast, water generally has a lower concentration of ions, resulting in reduced conductivity and, therefore, lower voltage generation.
What compound is the source of electrons for linear electron flow?
In linear electron flow in the light reactions of photosynthesis, water is the source of electrons. The process involves the splitting of water molecules to release electrons, which are then used to reduce the electron carrier molecules in the electron transport chain.
What refers to electric current when electrons always flow in the same direction in the wire?
Direct current (DC) refers to electric current where electrons always flow in the same direction in the wire. This is in contrast to alternating current (AC), where the flow of electrons periodically reverses direction. DC is commonly used in batteries and electronic devices that require steady and constant voltage.
How does flow of electrons in an electrochemical cell differ from that in a PV cell?
In an electrochemical cell, the flow of electrons occurs through an external circuit as a result of a redox reaction, where oxidation and reduction happen in separate electrodes. In contrast, a photovoltaic (PV) cell generates electrons through the absorption of sunlight, creating an electric current as electrons are excited and flow through a semiconductor material. While both systems involve the movement of electrons to generate electricity, the driving forces behind their electron flow are fundamentally different: chemical reactions in electrochemical cells versus photonic excitations in PV cells.
Electrons from what replace the electrons form photosystem 2 during non cyclic electron flow?
During non-cyclic electron flow, electrons come from water molecules that are split by photosystem II. These electrons replace the ones lost by photosystem II as they are passed along the electron transport chain.
What map is use to compare and contrast?
A Venn diagram can be used to compare and contrast two or more topics, showing similarities and differences in a visual way.
How are electrons and water alike?
they both flow
Flow of water and electric current is compared to?
The flow of water is often compared to the flow of electric current. In both cases, the flow is the movement of a substance (water or electrons) from one point to another. The pressure difference in water systems is analogous to the voltage difference in electrical systems, and the flow rate in water systems is similar to the current in electrical systems.
Electrons from what replace the electrons from photosystem 2 during noncyclic electron flow?
water
USing the theory called electron flow concept means that electrons flow from?
The electron flow concept states that electrons flow from the negative terminal to the positive terminal of a voltage source, in contrast to the conventional current flow theory which assumes positive charge carriers moving from positive to negative.
Electrons form replace the electrons from photosystem 2 during noncyclic electric flow?
water
Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?
water
The flow of electrons is a lot like the flow of what?
The flow of electrons is a lot like flow of fluid particles(say water particles). This is based upon the so called "hydrostatic analogy" of electrical circuits.
How did the voltage produced by the two metals in water compare to when the metals were in the fruit e?
The voltage produced by the two metals in water is typically lower than when they are placed in fruit. This is because the acidic or electrolyte properties of the fruit enhance the electrochemical reaction between the metals, allowing for a more efficient flow of electrons. In contrast, water generally has a lower concentration of ions, resulting in reduced conductivity and, therefore, lower voltage generation.
Positive ions and electrons can flow in a a solution but only electrons can flow in wires. What causes the electrons to move?
In wires, the movement of electrons is driven by an electric field created by a voltage source. This electric field exerts a force on the electrons, causing them to move. In contrast, in a solution, positive ions and electrons can move because of the flow of electric current through the solution.
Metal taps a insulator or a conductor?
Metal is a conductor of electricity, meaning it allows the flow of electrical current. This is due to the free movement of electrons within the metal structure. In contrast, insulators do not allow the flow of electricity and prevent the movement of electrons.
What compound is the source of electrons for linear electron flow?
In linear electron flow in the light reactions of photosynthesis, water is the source of electrons. The process involves the splitting of water molecules to release electrons, which are then used to reduce the electron carrier molecules in the electron transport chain.
