Question

the current is measured across each of three positions as shown in the diagram. which current reading will be lowest?
they will be the same.
current measurement 1
current measurement 3
current measurement 2

Explanation:

This is a parallel circuit. In a parallel circuit, the total current from the source splits into separate branches. Current 1 measures the total current from the battery, which is the sum of the currents in all branches. Current 2 measures the sum of currents in two branches, and Current 3 measures the current in only one branch. The more branches included in the measurement, the higher the current reading.

Answer:

Current measurement 3
