Question 9 of 25

Each circled letter in the circuit diagram represents a meter that is used to
measure a quantity in the circuit. Which meters will measure current?
m
O A. C and D
B. B and D
OC. A and B
OD. A and C

Answer 1

A. C and D

Step-by-step explanation:

In the given options, the letters A, B, C, and D represent different meters used to measure quantities in the circuit. The question specifically asks which meters will measure current. In electrical circuits, current is the flow of electric charge. It is typically measured using a device called an ammeter. Therefore, we need to identify which meters among A, B, C, and D represent ammeters. Option A states that meters C and D will measure current. So, according to option A, both meters C and D are ammeters.

Option B states that meters B and D will measure current. This option does not match the correct answer because meter B is not mentioned as an ammeter.

Option C states that meters A and B will measure current. This option does not match the correct answer because meter A is not mentioned as an ammeter.

Option D states that meters A and C will measure current. This option does not match the correct answer because meter C is mentioned as an ammeter, but meter A is not.

Therefore, based on the given options, the correct answer is:

A. C and D

Answer 2

D

Step-by-step explanation:

The meters labeled A and C will measure electric current flowing in the branch they are connected in series with the other electric elements.

The meters B and D are connected in parallel with resistors. They are expected to measure the potentials across the resistances.
