That really depends what information you have. One formula that is often used is:
P = IV (power = current x voltage)
Actually you should also multiply a power factor, but this power factor is one for DC, and it is often close to one for AC.
From there, you can calculate energy (power x time).

What does a light bulb in an electrical circuit transform to?
A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).
What type of energy flows in a circuit?
Electrical energy flows in a circuit, which is the movement of electrons through a conductor like a wire. This flow of electrons creates an electric current that powers devices connected in the circuit.
What is the formula for calculating the resistance in an electrical circuit?
The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
What energy conversion ooccur when a switch is closed?
When a switch is closed, electrical energy is converted into other forms of energy depending on the circuit. For example, in a light bulb circuit, electrical energy is converted into light and heat energy. In an electric motor circuit, electrical energy is converted into mechanical energy.
What type energy flows in a circuit?
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.
What is the formula for potential energy in an electrical system?
In an electric circuit, potential energy is usually understood as "stored charge." This is what capacitors do.
What does a light bulb in an electrical circuit transform to?
A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).

How do you get energy from batteries?
You hook them up to an electrical circuit, and the energy would appear as electrical energy that the circuit can then transform into some other format.

What is the significance of the battery electrical symbol in circuit diagrams?
The battery electrical symbol in circuit diagrams represents a power source that provides electrical energy to the circuit. It is significant because it shows where the energy in the circuit comes from and helps in understanding how the circuit functions.
How does the battery symbol in a circuit diagram represent the flow of electrical energy within the circuit?
The battery symbol in a circuit diagram represents the source of electrical energy in the circuit. It shows the direction in which the electrical energy flows, from the positive terminal of the battery to the negative terminal, providing power to the components in the circuit.
What type energy flows in a circuit?
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.
Is electrical energy potential, kinetic, or both in a closed circuit system?
In a closed circuit system, electrical energy is both potential and kinetic.
How do batteries function within an electrical circuit?
Batteries function within an electrical circuit by converting chemical energy into electrical energy. When connected to a circuit, the battery's chemical reactions create a flow of electrons, which generates a voltage that powers the circuit.
What does a speaker do in a circuit?
It converts electrical energy to sound energy.
