Answer:
C. increases
Explanation:
The total resistance of a parallel circuit is given by:
[tex]\frac{1}{R_T}=\frac{1}{R_1}+\frac{1}{R_2}+...[/tex]
where R1, R2, etc. are the individual resistances.
From the formula, we notice that as new resistors are added to the configuration, the total resistance [tex]R_T[/tex] decreases.
According to Ohm's law, the current flowing in the circuit is inversely proportional to the total resistance:
[tex]I=\frac{V}{R_T}[/tex]
where V is the voltage supplied by the source: so, when adding more resistors in parallel, the total resistance decreases and the current increases.
Finally, the power supplied by the source is
[tex]P=VI[/tex]
we said that V (voltage) remains constant, while I (the current) increases, so the power supplied increases as well.
