Vedclass · Answer

(C) $1$. An ideal battery maintains a constant potential difference $V$ across its terminals regardless of the current drawn.$2$. When a second resistor is connected in parallel with the first resistor $R$,the total equivalent resistance $R_{eq}$ of the circuit decreases,as $1/R_{eq} = 1/R + 1/R_2$.$3$. Since the battery is ideal,the potential difference across the original resistor $R$ remains unchanged $(V)$. Therefore,the current through $R$ $(I = V/R)$ remains constant.$4$. However,the total current delivered by the battery is $I_{total} = V/R_{eq}$. Since $R_{eq}$ decreases,the total current $I_{total}$ increases.$5$. Thus,the correct statement is that the current delivered by the battery will increase.

$A$ simple circuit contains an ideal battery and a resistance $R$. If a second resistor is placed in parallel with the first,which of the following statements is correct?
