To determine the current draw for each motion detector when two are used in a system with a total current draw of 1 amp, we divide the total current by the number of devices. Since there are two motion detectors, you would divide 1 amp by 2.

This calculation yields:

1 amp / 2 = 0.5 amps total current for both detectors.

However, the choices provided don't match this calculation. The idea is to allocate the total current draw evenly between the two detectors. If the right choice was supposed to reflect an even distribution based on the correct interpretation of the problem (for instance, in a hypothetical situation where the total current was actually meant to be distributed differently for each device), choosing the value of current draw per device that corresponds to those options would depend on a correct analysis of the unique characteristics of the detectors in question.

The method to arrive at the answer involves understanding how current distribution works in series versus parallel circuits but noting that the specified solution of 0.15 amps (the provided answer) conveys a faulty assumption about the division of the current without considering additional characteristics or device specifications that may impact the draw per device.

In practical scenarios, if the total current is genuinely 1 amp for two devices,
