Energy Charge Voltage Calculator
Enter the values of change in electric potential energy, dPE(J) and electric charge, q(C) to determine the value of Change in voltage, dV(V).
Energy Charge Voltage Formula:
Energy charge voltage is a fundamental concept in electrical engineering and physics, particularly concerning the relationship between electric potential energy and electric charge.
It describes the change in voltage (electric potential difference) when an electric charge moves in an electric field, reflecting the potential energy per unit charge.
This concept is crucial for understanding how electric fields influence charged particles and for analyzing electric circuits and systems.
Change in voltage, dV(V) in volts is calculated by dividing the change in electric potential energy, dPE(J) in joules by electric charge, q(C) in coulombs.
Change in voltage, dV(V) = dPE(J) / q(C)
dV(V) = change in voltage in vlts, V.
dPE(J) = change in potential energy in joules, J.
q(C) = electric charge in coulombs, C.
Energy Charge Voltage Calculation:
- Calculate the change in voltage when an electric charge of 2 coulombs experiences a change in potential energy of 10 joules:
Given: dPE(J) = 10J, q(C) = 2C.
Change in voltage, dV(V) = dPE(J) / q(C)
dV(V) = 10 / 2
dV(V) = 5V.
- Determine the change in potential energy for a charge of 3 coulombs moving through a potential difference of 4 volts:
Given: dV(V) = 4V, q(C) = 3C.
Change in voltage, dV(V) = dPE(J) / q(C)
dPE(J) = dV(V) * q(C)
dPE(J) = 4 * 3
dPE(J) = 12J.
Applications and Considerations:
- Electric Fields: Understanding energy charge voltage helps in analyzing the behaviour of charges in electric fields.
- Circuit Design: Voltage calculations are crucial for designing circuits that manage energy efficiently.
- Capacitors: In capacitors, the relationship between charge, voltage, and stored energy is fundamental for their operation.
