What else can I help you with?
Is it true that A light bulb converts electrical energy into both heat and light energy.?
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.
Is it true a light bulb acts as resistor in the flow of electrons?
While a light bulb does not technically act as a resistor, in practice it does impede the flow of electrons due to its resistance. As electrons pass through the filament of the light bulb, they encounter resistance, which causes them to release energy in the form of heat and light. This phenomenon is what allows the light bulb to produce light.
Is it true that Thomas Edison invented the light bulb?
While Thomas Edison is often credited with inventing the light bulb, the light bulb was actually developed by several inventors before him. Edison improved upon existing designs and was able to make the light bulb practical for everyday use by developing a long-lasting and reliable filament.
When light strikes the a material and most of the light is absorbed or reflected what optical must the material have?
The material must have a high level of opacity to absorb or reflect most of the light. The opaque nature of the material prevents light from passing through it, leading to absorption or reflection.
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.
Based on what you have seen what must be true for a circuit to light a bulb?
There must be a current through the bulb in order for it to glow.
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.
If one light bulb is removed from a parallel circuit with three bulbs the brightness of the other bulbs will decrease True or false?
False. In a parallel circuit, each light bulb operates independently, so removing one bulb does not affect the brightness of the others. The remaining bulbs will continue to receive the same voltage as before, maintaining their brightness.
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.
Is it true that A light bulb converts electrical energy into both heat and light energy.?
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.
Is it true that a light bulb converts electrial energy into electromagnetic energy?
True. Light is a form of electromagnetic energy.
Edison's light bulb and Bell's telephone revolutionized communication?
True
Were was the light bulb invented?
Henricg Globel invented the first true light built in 1854 in Germany.
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.
True or False The voltage rating of a fuse can be greater than the circuit voltage?
True. The voltage rating of a fuse must be greater than the circuit voltage.
Is it true that a person died from electrocution after putting a light bulb in their mouth, as claimed by a popular urban legend debunked by Snopes?
Yes, it is not true that a person died from electrocution after putting a light bulb in their mouth, as debunked by Snopes.
