NO. Electricity is NOT instantaneous.

Light has finite velocity 3 x 10^8 m/s.

Nothing can travel faster than light. Means everything has finite velocity less than light. Nothing travels instantaneously. Hence electrons have finite velocity too.

NO. Electricity is NOT instantaneous.

Light has finite velocity $3 \times 10^8\ \rm m/s$.

Nothing can travel faster than light. This means everything has finite velocity less than light. Nothing travels instantaneously. Hence electrons have finite velocity too.
