Students are building basic circuits in their physics class and they are asked to measure the current running through their circuit which includes a battery and a single resistor. Which of the following will they need to do to get an accurate reading for current?

A. Students will need to use a voltmeter and touch it on either side of the battery to measure the current.
B. Students will need to use a voltmeter and touch it on either side of the resistor to measure the current.
C. Students will need to use an ammeter and touch it on either side of the resistor to measure the current.
D. Students will need to make the ammeter a component built into their circuit so that electrons flow through it to measure the current.

Answer:

Students will need to make the ammeter a component built into their circuit so that electrons flow through it to measure the current. The correct option is D

Explanation:

Electric current can be defined as the flow of charge through a wire in a region. The electric current can create light used in bulbs and magnetic fields used in inductors and transformers. The Standard International (S.I) unit for electric current is Ampere. The instrument used for the measurement of electric current is an AMMETER.

In the construction of a basic circuit, which is complete and closed path through which electric current can flow, the following is needed by the physics student:

-an energy source (AC or DC),

-a conductor (wire),

-an electrical load (device), and

-at least one controller (switch).

When asked to measure the current that is flowing through the circuit, an AMMETER needs to be introduced which will be built into their circuit so that electrons flow through it to measure the current. I hope this helps thanks.
