What causes sparking at the brushes in amotor?
It has static charges. Or it may be combustible, that's why it spark and went to flame.
What are some examples of indirect contact?
Some examples of disease spread through indirect contact and agents are as follows; Bacteria. E.coli causes food poisoning and urinary tract infections. Mycobacterium tuberculosis causes tuberculosis. Viruses Influenza virus causes 'flu'. Herpes simplex virus causes herpes. Protozoa Plasmodium causes malaria. Fungi Tinea causes ringworm.
What causes the ripple voltage on the output of a capacitor-input filter?
Ripple voltage in a capacitor-input filter primarily arises from the charging and discharging cycles of the capacitor. When the rectifier conducts, the capacitor charges to the peak voltage of the input signal. As the load draws current, the capacitor discharges, causing the voltage to drop until the rectifier conducts again, resulting in a voltage ripple. The magnitude of this ripple depends on factors such as the load current, capacitance value, and input frequency.
What Causes of mining?
Illegal mining is acknowledged to be one of the major causes for coal fires. Considering, coal tendency to heat when placed in contact with an oxygen source, illegal mining directly contributes to this massive pollution source
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
What is charging a neutral object by bringing it close to a charged object called?
Inducing a charge by bringing a neutral object close to a charged object is called electrostatic induction. This process causes the redistribution of charges within the neutral object, resulting in the neutral object acquiring a charge.
What causes electrical charging object?
Objects become charged when they gain or lose electrons. This can happen through friction (rubbing two materials together), conduction (direct contact with a charged object), or induction (influencing the distribution of charges in an object without direct contact).
What are three ways static electricity be produced?
Static electricity can be produced through friction, where two materials rub against each other and electrons transfer between them. It can also be generated by conduction, where a charged object comes into contact with a neutral object and causes charge to redistribute. Lastly, static electricity can be induced by polarization, where a charged object interacts with a neutral object and causes the charges within the neutral object to rearrange.
What are the negative impact of decreasing the interest rate?
1) Decrease in the value of savings causes redistribution of assets. This redistribution has associated costs.2) Increased consumption due to the increased cost of savings causes inflation.
What happens when a charged object is brought near a metallic object that is not charged?
When a charged object is brought near a neutral metallic object, the charges in the metallic object redistribute themselves. This causes the charges within the metallic object to separate, with opposite charges being attracted to the charged object. This redistribution of charges induces a temporary charge separation in the metallic object, known as polarization.
What will happen if during induction the ground connection was removed first before the charging body?
During induction, if the ground connection was removed first before the charging body, the electrons on the electroscope will be stranded. This causes a negative charge on the object.
What are four types of static electricity?
Frictional static electricity: generated when two surfaces rub against each other. Contact static electricity: occurs when two different materials touch and electrons transfer between them. Induction static electricity: produced when a charged object causes a separation of charges in a neutral object without direct contact. Capillary static electricity: results from the movement of liquids in tiny tubes due to electron redistribution.
What causes the charges in atomic particles?
arrangement of leptons and quarks in sub atomic particle causes charges in then.
Is charging of car battery chemical change?
Yes. The charging causes a chemical change in the electrolyte of the battery.
How can objects charge?
Objects can become charged through friction, conduction, or induction. Through friction, electrons can be transferred between two objects by rubbing them together, resulting in one object becoming positively charged and the other negatively charged. In conduction, charges are transferred when objects come into direct contact with each other. Induction involves creating a charged region on an object without direct contact by bringing a charged object close to it, which causes a redistribution of charges within the object.
Why Electric Field is zero inside a charged isolated conductor?
Because in a charged isolated conductor charges are distributed equally into all the sides of a conductor, and also it contains both positive and negative charges, so the opposite forces of each charges cancel each other, that's why E is zero..
What causes a substance to have a positive charge?
the object has to have more positive charges than negative charges.
