Beside the power using device .e. a light bulb in the circuit, the circuit also need to use some of the power from the power souce to move the current along the wiring (the circuit) therefore for there is a natural drop in the amount of energy.
All electical circuits have a resistance, this requires some of the power to be used to carry the current to its final destination (in our case the bulb)
To see this in a simple experiment. Using a hose pipe attached to a water outlet. make small holes in regular stages along the pipe. Block the end of the pipe and turn on the water supply. You will see that more water comes from the holes closer to the water source than the latter holes in the pipe. This is because more water (energy) escapes
What else can I help you with?
Why does the voltage need to be so high in a power station?
In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.
What is always loss during a transfer of energy?
ENERGY
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
The rate of heat loss from the hot cup change during the experiment answer?
The rate of heat loss from the hot cup decreased during the experiment.
Explain the factors that account for the loss of energy in the transfer from mouse to cat?
The mouse use some energy is used in respiration(loss as heat) and the others used as growth( which will then pass on to the cat)

Who oppose the flow of eletricity current in resistance?
Opposition to the flow of electric current in a resistance is caused by the collisions of the electrons with the atoms in the material. This interaction converts some of the electrical energy into heat, leading to a loss of energy through the resistance.
How does an energy circit flow?
In an incandescent bulb, the current flows through a thin tungsten wire or a metallic filament that offers high resistance to current flow. When the electrons bump into the atoms, the friction, or loss of kinetic energy, produces heat
How does a resistor slow down the flow of change in a circuit?
A resistor slows down the flow of current in a circuit by converting electrical energy into heat. This conversion of energy leads to a loss in voltage, limiting the speed at which the current can flow through the circuit. The resistance in the resistor opposes the flow of current, reducing its rate of change.
What is hystersis loss?
As the emf in an AC circuit causes current flow in the core of an inductor the magnetic dipoles will align themselves with the direction of the flow. As the current reverses the dipoles tend to stay aligned and there is a certain amount of flow that is required to realign them in the opposite direction. Thus there is a lag between current reversal and dipole realignment. The energy used for this realignment so to speak is called hysterisis and is a loss to the circuit.
What is conductor loss?
Conductor loss refers to the energy dissipated as heat in a material due to the flow of electric current. It is caused by the resistance of the conductor and is proportional to the square of the current flowing through it. This loss results in decreased efficiency in electrical systems and can lead to overheating if not properly managed.
What is the effect of changing the thickness of the wire?
Changing the thickness of the wire will affect its resistance. Thicker wire has lower resistance, allowing more current to flow through it with less energy loss as heat. Thinner wire has higher resistance, restricting the flow of current and causing more energy to be lost as heat.
What is always loss during a transfer of energy?
ENERGY
Resistance to the flow of electrons in a conductor causes a loss of?
Energy as heat
Why do power lines have a high voltage in order to minimize current and heat loss?
Power lines have a high voltage to reduce the amount of current flowing through them, which helps to minimize heat loss and energy waste during the transmission of electricity.
What are the differences between laminar flow and turbulent flow in fluid dynamics?
Laminar flow is smooth and orderly, with fluid moving in parallel layers, while turbulent flow is chaotic and unpredictable, with swirling and mixing of fluid. Laminar flow has low energy loss and is easy to predict, while turbulent flow has high energy loss and is harder to predict.
What are the functions of conductors?
Conductors are materials that allow the flow of electric current. They are used to connect electrical components in circuits and facilitate the transfer of electricity. Conductors also distribute electrical energy efficiently and effectively.
