Electricity is the set of physical phenomena that are associated with the presence and flow of electric charge. In the case of the Electrical Age mod, electricity is used as electrical power.

Voltage

The Volt is the unit for electrical potential. It measures the difference in electrical potential between 2 points.

Calculation

If the resistance and current of the circuit is known voltage can be calculated using the formula V = IR.

Current

Current, or amperage, is the flow of electrical charge. Current is measured in units called Amperes. 1 Ampere is equivalent to 1 Coulomb per second. Currents can create magnetic fields, which can be used in inductors, motors, and generators. Electric currents also cause heating, which can be used to create light.

Calculation

If the voltage and resistance of the circuit is known the amperage can be calculated using Ohm's law: I = V/R.

Resistance

Electrical resistance, is a measure of how difficult it is for electricity to move through a circuit. Measured in Ohms.

Calculation

If the voltage and current of the circuit is known, and V and I are directly proportional, the resistance can be calculated as R = V/I. In the case of batteries or diodes, V and I will not be directly proportional, however this formula may still be useful for calculating the static resistance.

Electric Power

Electrical power is the rate at which a circuit transfers energy. This can be measured in Joules and watts. Joules are how much energy is within a point at any given time. Watts are simply Joules in motion: Equal to 1 Joule over 1 second.

Calculation

Wattage can be calculated using the formula Power = Voltage * Current (P = VI).
