Question

Express 1.2 × 10-3 amps in milliamps (1 milliamp equals 1 × 10-3 amps). Choice 'A'1.02 × 100 milliampsChoice 'B'1.2 × 101 milliampsChoice 'C'1.2 × 100 milliampsChoice 'D'1.02 × 101 milliamps

Answer 1

Given expression is

`1.2*10^(-3)\text{ amps}`

given 1 milliamp =1*10^-3 amps.

So, 1 amps=10^3 miliiamps.

So,

`\begin{gathered} 1.2*10^(-3)=1.2*10^(-3)*10^3 \\ =1.2 \end{gathered}`

As per the calculations, and the instruction given in the question, after expressing the given expression in milliamps, the final value should be 1.2

So, no option is correct.
