Questions & Step-by-Step Solutions

What is the final charge (Q) on a capacitor in an RC circuit when a voltage (V) is applied?
  • Step 1: Understand that a capacitor is a device that stores electrical energy.
  • Step 2: Know that the amount of charge (Q) a capacitor can hold depends on two things: its capacitance (C) and the voltage (V) applied to it.
  • Step 3: Remember the formula that relates charge, capacitance, and voltage: Q = CV.
  • Step 4: Identify the values you have: the capacitance (C) of the capacitor and the voltage (V) applied.
  • Step 5: Multiply the capacitance (C) by the voltage (V) to find the final charge (Q) on the capacitor.
