What is amperage, and what is its relationship to voltage and power?

Amperage is the rate of electrical charge per time.

1 amp = 1 coulomb / second

Power is the product of amperage and voltage.

P = IV

P = i V

Explanation:

Electrical power is the rate of work done against electrical forces

So we know that here in electrical circuits the work done to move the charge from initial to final position is given as

so here we need to find the electrical power

so it is given as

we know that rate of flow of charge is electric current

so we have

P = i V

found in the nucleus

has mass of one amu

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
