One ampere equals
a)106μA{{10}^{6}}\mu A
b)10−6μA{{10}^{-6}}\mu A
c)10−3μA{{10}^{-3}}\mu A
d)10A10A

Explanation

Solution

One Ampere (A): One Ampere is defined as the current that flows with electric charge of 1 Coulomb per second. So, we can say that: 1A=1C1s1A=\dfrac{1C}{1s} . Also, we know that 1μ=10−61\mu ={{10}^{-6}}. Using the relations, compute the value of 1 Ampere in μA\mu A as required.

Complete step by step answer: As We know that: 1μ=10−61\mu ={{10}^{-6}}
So, for a quantity of current, we can have: 1μA=10−6A1\mu A={{10}^{-6}}A
Therefore, we can say that, 1A=106μA1A={{10}^{6}}\mu A
Hence, the correct answer is the option (a).

Additional information:
a) One coulomb (C): One Coulomb is equal to the charge transfer in a metal in one second while constantly 1 Ampere of current flows through it.
b) One Ampere (A): One Ampere is defined as the current that flows with electric charge of 1 Coulomb per second.
c) One volt (V): One Volt is defined as energy consumption of 1 Joule per electric charge of 1 Coulomb.
d) One Ohm (Ω): One Ohm is the resistance of a conductor such that when a potential difference of 1 Volt is applied to its ends, a current of 1 Ampere flows through it.

Note: While converting one unit to another, be careful with the standard values of each unit. For example, 1μ=10−61\mu ={{10}^{-6}} or 1m=10−31m={{10}^{-3}}. Do not mix up various quantities. Students might only get an error while remembering the standard quantities of the units.
