CAIE A-Level Physics AS 10.2.2 Kirchhoffs Second Law and Understand That It Is a Consequence of Questions question 1

[Maximum number: 1]

Three resistors, R1,R2R_{1}, R_{2} and R3R_{3}, are connected in parallel to a cell. The currents in the resistors are I1,I2I_{1}, I_{2} and I3I_{3}. The potential differences across the resistors are V1,V2V_{1}, V_{2} and V3V_{3}. The current in the cell is I0I_{0}. The potential difference across the cell is V0V_{0}, as shown.
