Questions & Step-by-Step Solutions

If a capacitor is charged to a voltage of 10V and has a capacitance of 5μF, what is the charge on the capacitor? (2022)
  • Step 1: Identify the values given in the problem. The voltage (V) is 10 volts and the capacitance (C) is 5 microfarads (μF).
  • Step 2: Convert the capacitance from microfarads to farads. 5 μF = 5 x 10^-6 F.
  • Step 3: Use the formula for charge (Q) on a capacitor, which is Q = C * V.
  • Step 4: Substitute the values into the formula: Q = (5 x 10^-6 F) * (10 V).
  • Step 5: Calculate the charge: Q = 5 x 10^-5 C.
  • Step 6: Convert the charge from coulombs to microcoulombs. 5 x 10^-5 C = 50 μC.
