Electrostatics, Circuits & Electrodynamics is one of 9 topics in the Grade 12 Technical Sciences CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. Which formula defines capacitance C?
C = Q/V
C = V/Q
C = QV
C = Q + V
Answer: C = Q/V — Capacitance is defined as C = Q/V, the ratio of stored charge to applied voltage.
Easy
2. What is the SI unit of capacitance?
Farad (F)
Coulomb (C)
Volt (V)
Ohm (Ohm)
Answer: Farad (F) — Capacitance is measured in farads (F).
Medium
3. A capacitor stores a charge of 0,006 C when a voltage of 12 V is applied across it. Calculate its capacitance, in F.
Answer: 0.0005 — C = Q/V = 0,006/12 = 0,0005 F (5 x 10^-4 F).
