# Voltage

- Electricity: Joules to Volts - Convert energy in joules to electrical potential in volts by dividing the energy by the charge. This tool helps with electrical engineering calculations.
- Hall Effect Voltage - The Hall effect voltage is a key phenomenon in magnetism and electronics. This equation calculates the Hall voltage generated across a conductor in a magnetic field.
- Kirchhoff's Voltage Law (KVL) - Kirchhoff's Voltage Law (KVL) is used to calculate the sum of all voltages around a closed loop in an electrical circuit. Learn about the formula and its practical applications.
- Ohm's Law - Ohm's Law relates the current flowing through a conductor to the voltage and resistance, fundamental in electrical engineering.
- Power from Current and Voltage - Calculate electric power in watts given the current in amperes and the voltage in volts using the formula P = I × V. Find out how much electrical power is being transferred in a circuit.
