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 else can I help you with?
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
What are causes of change in voltage of alternators when loaded?
actully when load of alternator fluctuates it changes the torque at primovers which changes amps so terminal voltage of alternator changes.
How does load current vary with the load resistance?
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
A devise that increases or decreases the voltage of alternating current?
TRANSFORMER
What increases when the resistance of an electrical circuit decreases?
Current increases if the voltage remains constant.
An electrical tool that increases or decreases the voltage in an electrical current is?
capacitors
Why terminal voltage of a self excited shunt generator decreases with an increase of load?
The terminal voltage of a self-excited shunt generator decreases with an increase in load due to an increase in voltage drop across the internal resistance of the generator. As the load current increases, the drop across the internal resistance also increases, reducing the output voltage available at the terminals. This effect is known as voltage regulation and is a common characteristic of self-excited shunt generators.
Does electrical current generally increase as resistance decreases?
Ohm's Law Voltage = Current x Resistance. So for a fixed voltage as R decreases then current increases proportionally.
Why terminal potential difference is decrease when current in the circuit is increased?
The terminal potential difference decreases when the current in the circuit is increased due to the internal resistance of the power source. As the current increases, the voltage drop across the internal resistance also increases, leading to a decrease in the terminal potential difference available to the external circuit. This is described by Ohm's Law, V = E - Ir, where V is the terminal potential difference, E is the electromotive force of the source, I is the current, and r is the internal resistance.
How are current and voltage related are they directly proprtional or inversely proportional?
Current and voltage are directly proportional according to Ohm's Law. This means that as voltage increases, current increases proportionally, and as voltage decreases, current decreases proportionally. Mathematically, this relationship is expressed as I = V/R, where I is current, V is voltage, and R is resistance.
When resistance decreases what happens to current?
Based on the simplest Electrical Equation V = I * R,(reads: voltage equals current multiplied by resistance)then, rearranged I = V / R .As resistance decreases, current flow proportionately increases
In 3 phase voltage increases and current decreases why?
If the load current descrease, there is less voltage drop caused by the resistance of the wire, so the voltage is higher.
Which law says voltage increases current decreases?
Ohm's law says the opposite.
Is voltage directly or inversely proportional?
Voltage is directly proportional to current, meaning that as voltage increases, current also increases and vice versa, as per Ohm's Law. However, voltage is inversely proportional to resistance, meaning that as voltage increases, resistance decreases and vice versa.
