Question

Coulomb is the unit of charge while ampere is the rate at which it flows. If true enter 1, else enter 0.

Answer 1

Hint: Here both coulomb and ampere are SI units. Coulomb is the SI unit of charge. When charges move it is called current and ampere is the SI unit of current. The statement given above says the same.

Complete answer:
The answer is 1, it is true. Coulomb is the unit of charge. Coulomb is the SI unit of charge. Coulomb is defined as the quantity of electricity transported in one second by a current of one ampere. It is denoted by “C” . One coulomb is calculated as, 1C= 1A*1S, where C is coulomb, A is ampere and S is second.
One coulomb of electrical charge, or 6.25X ${10^{18}}$ electrons, travelling in one second is represented by one ampere of current. In other terms, one ampere is the amount of current generated by one volt acting through one ohm of resistance. Charge on an electron is \[1.60217662{\text{ }} \times {\text{ }}{10^{ - 19}}\;\] coulombs. The ampere is defined as the constant current that, if maintained in two straight parallel conductors of infinite length, insignificant circular cross-section, and placed one metre apart in vacuum, produces a force of $2 \times {10^{ - 7}}$ newtons per metre of length between them.

Note:
One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 10-19 C. A typical lightning bolt will have 30,000 ampere of current in them while the current we get to our house is 15 ampere. A current of above 10 amperes can be fatal for human beings.
