What happens when the circuit is closed?
When a circuit is closed, it forms a complete path for the flow of electric current from the power source (such as a battery) through the circuit components (resistors, capacitors, etc.) and back to the power source. This allows electrical energy to be transferred and used to power devices connected to the circuit.
What happens when a battery is hooked up to an open circuit?
When a battery is hooked up to an open circuit, no current flows because the circuit is not complete. The voltage across the open circuit is equal to the battery voltage, but no electrical work is done since there is no flow of electrons. The energy stored in the battery remains as potential energy until a complete circuit is established.
What happens when an electric current enters leaves?
When an electric current enters a component, it carries energy and can cause the component to perform a function, such as generating light or heat. When the current leaves the component, it has already expended some of its energy, so the effect on the circuit or device may be different.
Does current or voltage actually perform the work in a circuit?
Voltage is what drives the current to flow in a circuit, so it provides the potential energy to do work. The current then carries that energy through the circuit to power devices or perform work, such as generating heat or light. Both voltage and current are essential for work to be done in a circuit.
True or false Moving current has electrical energy?
True. Moving current, such as in an electrical circuit, carries electrical energy in the form of kinetic energy of the moving charges.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
What do a resistor do in a circuit?
A resistor is a device that impedes or limits the flow of electrical current in a circuit. It converts the current's electrical energy into heat (thermal) energy. A resistor reduces the amount of energy in a circuit and pumps it out as a heat.

What happens to the energy in a circuit when the current passes through a component?
A: If there is resistance within the device it will cause to dissipate some of the energy as heat. The rest will continue

What is the flow of an electrical current in a circuit outside the power source?
Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.
1amp 1volt 1ohm travels at 186000 miles a second if you double the voltage does it double the speed in which it travels the circuit?
Doubling the voltage in a circuit does not double the propagation speed in that circuit. It only doubles the available energy (volts is joules per coulomb), which doubles the current (amperes is coulombs per second), and quadruples the power (watts is joules per second).
Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
What type of energy do the circuit the batteries in the circuit have?
Batteries have chemical energy stored inside them. Of course, when they provide a current, this chemical energy is transformed (in part) into electrical energy.
What device could not provide the energy for current to flow in a circuit?
a resistor
