Question

What value was measured for the elementary charge?

Options

• \[1.602 \times 10^{19}\ \text{C}\]

• \[1.602 \times 10^{-19}\ \text{C}\]

• \[3 \times 10^8\ \text{C}\]

• \[1.76 \times 10^{11}\ \text{C}\]

Answer 1

The elementary charge measured through Millikan’s oil-drop experiment is \[1.602 \times 10^{-19}\ \text{C}\]. Oil-droplet charges were integral multiples of this value.
