Three resistors are arranged as shown. The potential of the point O is:
Correct answer: A. 3 V
- A. 3 V
- B. 1 V
- C. 4 V
- D. 5 V
Explanation
To find the potential at point O, we apply Kirchhoff's Current Law (KCL), which states that the sum of currents entering a junction equals the sum of currents leaving the junction. Assuming I1, I2, and I3 are the currents through the resistors, KCL gives us: I1 + I2 + I3 = 0. Solving this equation with the given circuit values, we find that the potential at point O is 3 V. Options B (1 V), C (4 V), and D (5 V) are incorrect as they do not satisfy the KCL equation applied to this circuit.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
