Question

The diagram shows two resistors connected in parallel across a voltage source. Which statement is true for this circuit?

• A. The combined resistance is equal to the sum of the resistance
• B. The current at every point in the circuit is the same
• C. The current from the source is equal to the sum of the currents in X and in Y
• D. The sum of the potential difference across X and across Y is equal to the potential difference across the voltage source

Answer 1

The correct option is C The current from the source is equal to the sum of the currents in X and in Y

Both $X$ and $Y$ are in parallel so the total current delivered by source(battery) is divided into $X$ and $Y$. So total current from the source is equal to the sum of the currents in $X$ and in $Y$.
