What does current do in an electrical circuit?
Current is the flow of electric charge in an electrical circuit, carrying energy from a power source to the components in the circuit.
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.
How do resistors work in a circuit to regulate the flow of electric current?
Resistors work in a circuit by impeding the flow of electric current, which helps regulate the amount of current that passes through the circuit. They do this by converting electrical energy into heat energy as the current passes through them, which reduces the overall flow of current in the circuit. This helps control the voltage and current levels in the circuit, allowing for proper functioning of electronic devices.
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.
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 does current do in an electrical circuit?
Current is the flow of electric charge in an electrical circuit, carrying energy from a power source to the components in the circuit.
What does a resistor do in 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.
How does a resistor work in a circuit to regulate the flow of electrical current?
A resistor in a circuit works by impeding the flow of electrical current, which helps regulate the amount of current passing through the circuit. This is achieved by converting electrical energy into heat energy as the current passes through the resistor, limiting the flow of electricity.
Even without current flow there can be voltage in a circuit?
Voltage is potential energy and can exist in a open circuit.
