In a direct current (DC) circuit, electricity flows in a single, constant direction from the positive terminal to the negative terminal of the power source. The flow of electrons moves from the negative terminal to the positive terminal, but conventional current is defined as flowing in the opposite direction. DC circuits typically have a steady voltage, resulting in a consistent current, making them suitable for applications like batteries and electronic devices. The resistance in the circuit affects the current flow according to Ohm's Law, which states that current equals voltage divided by resistance (I = V/R).

What is true concerning a simple electric circuit?
The simplest form of an electrical circuit is when an energy source (such as a battery) is connected to a load (such as a light bulb or a resistor). The connections must be made in such a way as to allow the energy to flow from the source, through the load and back into the source to form a loop.
True or false A device that is used to open the circuit when the current flow is to great is a disconnect switch?
False. A device that is used to open the circuit when the current flow is too great is a circuit breaker or fuse.A disconnect switch is a manual device that isolates or turns off the load.
True are false. electricity is a flow of negative charge?
False. 1. Electricity involves the movement of electrical charges. The most common case is the movement of electrons (a negative charge), but other possibilities exist, such as movement of charges through ions (positive or negative), or holes (positive). 2. Even stating that electricity IS a flow of charged particles is a gross and misleading simplification. An electrical current INVOLVES the flow of charges, but that does not fully describe an electrical current.
What components must be present to have a true circuit?
A true circuit must have a power source (such as a battery or power supply), conductive path (wires or traces) for the current to flow, and at least one load (like a resistor, light bulb, or motor) that uses the electrical energy. Additionally, it must form a closed loop, allowing current to flow continuously. Without any of these components, the circuit will not function.
True or false in a series circuit circuit current is the same throughout the circuit?
A series circuit only has one loop
True or false a closed circuit is an incomplete loop?
False. A closed circuit is a complete loop where electricity can flow continuously from the power source, through the components, and back to the source.
What must be true for a circuit to light a bulb?
For a circuit to light a bulb, there must be a closed loop for the flow of electricity. This loop typically consists of a power source (e.g. battery), wires, a switch, and the bulb. When the switch is closed, the circuit is complete and electricity can flow through the wires to the bulb, causing it to light up.
Is it true or false that a switch is used to turn a circuit on or off?
It is true that a switch is used to open and close a circut.
Is true if there is voltage in circuit there must be electrons flowing through the circuit.?
No. For electrons to flow, you need a current.
Is it true that electric charges can flow through any of the pathways in a parallel circuit?
Yes, in a parallel circuit the electric charges have multiple pathways to flow through. This means that each component in the circuit will have its own separate pathway for the charges to travel through, allowing for different currents to flow through each branch of the circuit simultaneously.
Is it true that in a series circuit electric currents flow through more than one path?
more than 1
What happens to the flow of electricity in an incomplete circuit?
It stops flowing. An analogy to this is the kitchen faucet ... water is always "at the ready" behind the valve, ready to flow when it is enabled. Same is true in an electrical circuit - once the circuit is broken (valve closed in above analogy) the flow of electrons ceases. If there is a light bulb which is not on it is a open circuit. If the light bulb is still on it is parallel circuit which has lot of wires causes some of the lights to go on and some to go of.

Are Charges in an electric circuit flow because of a difference in electrical potential energy true or false?
TRUE
True or false The total current that flows through a circuit is the same as the current that flows through each individual parallel sub-circuit?
True
Is it true that an electrical insulator does not allow electricity to pass through it?
Yes, it is true.
True or false does a conductor allow electric current o flow through easily?
Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
