Why it is easier to lift the load in a wheelbarrow when the load is shifted towards the wheel?
If become easier to lift a load in a wheelbarrow when the load is towards wheel why
What will happen when source resistance equals load restiance?
when source resistance and load resistance are equal maximum power is transfered
Do charges move from a source of potential difference into a load or through both the source and the load?
As the circuit must be a closed loop, the current passes through both the source and load. If it was not a closed loop no current could flow anywhere.
Why peak voltage of the load is smaller than the voltage from the transformer output?
The voltage appearing across a load is always smaller than the no-load voltage of any voltage source -e.g. batteries, generators, or transformers. In simple terms this is because all these voltage sources have internal resistance or impedance which results in an internal voltage drop when the source delivers a load current. The resulting voltage, therefore, is always the difference between the no-load voltage and the internal voltage drop. A measure of the difference between a source's no-load and full-load voltage is termed its 'voltage regulation'.
When a source is delivering maximum power to load the efficiency of the circuit is always?
50%

Maximum power is transferred from a source to a load when the load resistance is equal to?
A:is equal to the source
Why is the above example a load or an energy source?
The above example is considered a load because it consumes energy from the source it is connected to. It draws power from the source to operate or perform its function. In contrast, an energy source is a provider of energy that can supply power to a load.
What is the difference between a hot wire and a load wire in electrical circuits?
In electrical circuits, a hot wire carries the electrical current from the power source to the device, while a load wire carries the current from the device back to the power source. The hot wire is typically black or red in color, while the load wire is usually white or gray.
What will happen when source resistance equals load restiance?
when source resistance and load resistance are equal maximum power is transfered
What load impedance Z will result in maximum power transfer from an electric source with an internal impedance of r?
For maximum power transfer, source resistance should match load resistance and source reactance should match load reactance with the opposite sign (so if the load is capacitive, the source should be inductive).
Do charges move from a source of potential difference into a load or through both the source and the load?
As the circuit must be a closed loop, the current passes through both the source and load. If it was not a closed loop no current could flow anywhere.
The object that uses up the energy being delivered in an electrical circuit is called the?
source
Why does the terminal voltage decreases as the load current increases?
A: That will happen anytime the voltage source is not able to provide the power needed for the load. If the load exceed the power available from the source the voltage will be reduced as IR drop from the source
What isconventional current flow?
conventional current flow means the natural tendency of a current to flow ie)source to load,towards low resistance,higher potential to lower potential
What is a static market?
A static market where one buyer faces a whole load of sellers.
Is loading effect more when load impedance is less then source impedance?
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
