Calculate the charge of the system?

Correct answer: C. 300C

  • A. 200C
  • B. 100C
  • C. 300C
  • D. 400C

Explanation

The correct answer is 300C. To calculate the total charge stored in the system, we first determine the total capacitance of the circuit. Since the capacitors are in parallel, their capacitances add up: C = C1 + C2 = 1F + 2F = 3F. The total potential difference across the capacitors is given as 100V. The charge stored (Q) is found using the formula Q = CV, which yields Q = 100V x 3F = 300C.Option A (200C) and Option B (100C) are incorrect because they likely result from errors in calculating the total capacitance or not using the complete voltage. Option D (400C) overestimates the charge, possibly due to miscalculation or incorrect assumptions about the circuit components.

About Electrostatics

Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
