What else can I help you with?
An electric current is produced when charges are accelerated by an electric field to move to a position of potential energy that is?
lower than their initial potential energy. The charges gain kinetic energy as they accelerate through the field, creating an electric current.
When A proton initially at rest falls through a p.d of 25000v .what speed does it gain?
The kinetic energy gained by the proton is equal to the work done on it by the electric field. Using the equation for work, you can find the final velocity of the proton. Given the potential difference (voltage) of 25000 V, you can calculate the speed gained by the proton.
Properties of electric charge?
Electric charge is a fundamental property of matter that can be positive or negative. Like charges repel each other, while opposite charges attract. The unit of electric charge is the coulomb, and it is conserved in isolated systems.
How can you show by simple experiment that there are two types of electric charges?
One simple experiment to show that there are two types of electric charges (positive and negative) is to rub a balloon with a wool cloth. The balloon will gain a negative charge, while the cloth will gain a positive charge. When the negatively charged balloon is brought close to small pieces of paper or dust, they will be attracted to the balloon, demonstrating the presence of opposite charges.
How does a free electron at rest move in an electric field?
A free electron at rest in an electric field will experience a force due to the field and will accelerate in the direction of the electric field. The electron will gain kinetic energy and start moving in the direction of the force until it reaches a velocity where the force due to the field is balanced by other forces acting on the electron.
How you can calculate the lay ratio of armour in electric cables?
armoured OD X 10 time and gain lay of armouring.
Why do you use logarithm to calculate gain of amplifiers?
Audio engineers talk about the "JND", which stands for "just notiecable difference", which is a 3 decibel gain. That 3 decibel gain requires a doubling of amplifier power. For an amp to sound, subjectively, "twice as loud" requires a tenfold increase in power (300 watts instead of 30 watts).The decibel scale is logarithmic, not arithmetic.
If a 13 dB gain antenna has 2 watts of power at the input what is the effective radiated power?
40 watts
How do you calculate capital gain on property?
To calculate capital gain on property, subtract the property's purchase price from the selling price. This difference is the capital gain.
All electric charges are do to a loss or gain of what?
electrons
How are dams useful info?
Of course it is, it help the world to gain electric and people can use the electric
How do you calculate the capital gain on the sale of a house?
To calculate the capital gain on the sale of a house, subtract the original purchase price and any expenses related to the sale from the selling price. The resulting amount is the capital gain.
How do I calculate my capital gains tax?
To calculate your capital gains tax, subtract the cost basis of your investment from the selling price to determine the capital gain. Then, apply the appropriate tax rate based on how long you held the investment and your income level.
How do you calculate capital gains on the sale of a second home?
To calculate capital gains on the sale of a second home, subtract the purchase price and any expenses related to the purchase and sale from the selling price. The resulting amount is your capital gain. This gain is subject to capital gains tax, which is based on the length of time you owned the property and your tax bracket.
How do you calculate capital gain for tax purposes?
To calculate capital gain for tax purposes, subtract the original purchase price of an asset from the selling price. If the selling price is higher, the difference is considered a capital gain and is subject to taxation.
How do you calculate the current gain of a transistor JFET?
FETs don't have current gain as no current flows through the gate. The gain of a FET is a voltage gain and is called mu.
What are electric charges answer?
Electric charge is the property of substance by virtue of it substance gain or loose electron if their is gain of electron then substance acquire negative charge if loose of elec then positive charge apper on it.
