Consider two charged balloons with charges of 1.0 × 10⁻⁶ C and 3.0 × 10⁻⁶ C. How many elementary charges do these balloons contain?
💡 Hint: Use the formula charge/elementary charge.
If the quantisation of charge indicates a minimum charge of 1.602 x 10⁻¹⁹ C, determine the number of electrons in a charge of -1.2 C.
💡 Hint: Divide the total charge by the elementary charge.
