Potential difference charge and Energy - Equation

Click For Summary
SUMMARY

The discussion centers on calculating the charge transferred during a lightning bolt with a potential difference of 13 MV and an energy release of 1.3 GJ. The relevant equation connecting energy (E), potential difference (V), and charge (q) is E = V * q. Using this equation, the charge can be calculated as q = E / V. The user confirmed their calculations and resolved their initial confusion regarding the conversion of units and the equation itself.

PREREQUISITES
  • Understanding of electric potential difference (voltage)
  • Familiarity with the relationship between energy, voltage, and charge
  • Basic knowledge of unit conversions in physics
  • Proficiency in algebraic manipulation of equations
NEXT STEPS
  • Study the derivation of the equation E = V * q
  • Explore examples of energy calculations in electrical systems
  • Learn about the physics of lightning and its energy transfer
  • Investigate unit conversion techniques in electrical engineering
USEFUL FOR

Students studying physics, electrical engineers, and anyone interested in understanding the principles of energy transfer in electrical phenomena.

Homework Statement


If the potential difference between a cloud and the ground is about 13MV , how much charge is transferred in a lightning bolt that releases 1.3GJ of energy?


Homework Equations





The Attempt at a Solution



1st can someone check my conversion - P.d=13*10^6V and E=13*10^9J
The main problem I have is that I don't know the equation relating E, P.V and q or if it exists... can someone please give me a hand... thanks
