In a capacitor, what is the relationship between charge (Q), capacitance (C), and voltage (V)?
  1. Q = C + V
  2. Q = C * V
  3. Q = V / C
  4. Q = C - V

Questions & Step-by-Step Solutions

In a capacitor, what is the relationship between charge (Q), capacitance (C), and voltage (V)?
  • Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
  • Step 2: Know the three important terms: charge (Q), capacitance (C), and voltage (V).
  • Step 3: Charge (Q) is the amount of electrical energy stored in the capacitor.
  • Step 4: Capacitance (C) is a measure of how much charge a capacitor can store per unit of voltage.
  • Step 5: Voltage (V) is the electrical potential difference between the two plates of the capacitor.
  • Step 6: The relationship between these three terms is expressed by the formula Q = C * V.
  • Step 7: This means that if you know any two of these values (Q, C, or V), you can calculate the third one.
