Question

A circuit is measured to have a current of 11.5 milliamperes. Which of the following values are equivalent to this measurement?

O 1150 amperes
O 1.15 10-2 amperes
O 0.0115 amperes
O 11.5 10-3 amperes
O 1.1510- amperes

Answer 1

11.5 milliamperes is equivalent to 0.0115 amperes. Option 3 is correct.

Step-by-step explanation:

An ampere is a unit used to measure electric current. It is defined as the amount of electric current that will produce an attractive force of 2.7 x 10^7 newtons per meter of separation between two parallel wires with an electric current running through them.

Given that the circuit in question has a current of 11.5 milliamperes (mA), we need to convert it to amperes (A) to determine which value is equivalent. 1 milliampere is equal to 0.001 amperes, so 11.5 milliamperes is equal to 11.5 x 0.001 = 0.0115 amperes.

Therefore, the value equivalent to a current of 11.5 milliamperes is 0.0115 amperes.

The student asks which of the following values are equivalent to a measured current of 11.5 milliamperes:

1150 amperes

1.15 × 10-2 amperes

0.0115 amperes

11.5 × 10-3 amperes

1.15× 10- amperes

To convert milliamperes to amperes, you must know that 1 milliampere (mA) is equal to 0.001 amperes (A). Therefore, 11.5 milliamperes equals 11.5 × 0.001 = 0.0115 amperes. So, the equivalent value in amperes to 11.5 milliamperes is 0.0115 amperes.
