Question 1

What is a volt?

Accepted Answer

A volt (V) is the SI unit of electric potential difference. 1 volt = 1 joule per coulomb.

Question 2

What is the difference between abvolt and statvolt?

Accepted Answer

Both are CGS system units. 1 abvolt = 10⁻⁸ V (CGS-EMU), while 1 statvolt ≈ 299.79 V (CGS-ESU).

Question 3

What common voltages are found in everyday life?

Accepted Answer

AA batteries provide 1.5 V, car batteries 12 V, household outlets 120 V (US) or 220–240 V (Europe), high-voltage power lines 110–765 kV, and lightning bolts can reach approximately 300 MV.

Question 4

How does voltage relate to energy and charge?

Accepted Answer

Voltage is defined as energy per unit charge: V = E/Q, where E is energy in joules and Q is charge in coulombs. It represents the "electrical pressure" that drives current through a circuit.
