(B)

Explanation:

i thing so it may be correct

answer

Answer 2

The ratio of voltage and electrical current in a closed circuit is (b) remains constant

Voltage definition:

• Voltage explains the “pressure” through which the  electricity is pushed.
• The quantity of voltage is indicated through a unit referred to as the volt (V)

Current definition:

• Current is defined as the rate at which electrons flows in a whole complete circuit.
• The quantity of current is indicated through a unit referred to as the Ampere (A)

Closed circuit:

• The closed circuit is a circuit in which there will be no interruption by providing a continuous way through which a current can pass.

Why the ratio of voltage and electrical current in a closed circuit is remains constant?

As a circuit is closed, the voltage cannot go out or come inside. So, the voltage throughout the circuit cannot increased or decreased, thus remain constant.

Therefore, the ratio of voltage and electrical current in a closed circuit is (b) remains constant.
