What else can I help you with?
What can you do to a closed circuit consisting of a battery a light bulb and a switch that would decrease the amount of current?
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.
Why we called zero bulb to zero volt bulb?
the zero bulb required less amount of electricty to glow the voltage of bulb is below 5 volt
Which device has its characteristics very close to that of an ideal current source?
A: A current source can be defined as a zero impedance source. A battery is essentially a zero impedance since it can provide lots of current with zero volts out
What is the volt of a zero watt bulb?
A zero watt bulb does not consume any power, so it does not have a voltage rating. Voltage is a measure of electrical potential difference, typically associated with the amount of energy transferred per unit charge. In the case of a zero watt bulb, there is no power being consumed, so there is no voltage required to power it.
Example of ideal constant-current source?
A current source ideally should be with an internal impedance of 0 zero. So even if the output is zero volts current can flow.
Why is there zero current when a light bulb out?
there is no voltage and resistance
What is the current of zero watts bulb?
zero
Why is there zero current when a lightbulb burns out?
because there is no voltage and resistance?
What is the starting and finishing energy of a light bulb?
Zero,because the distance has no affect to convert electric energy into light energy.

What is the current and voltage consumed by 0 watts bulb?
A zero-watt bulb is a lightbulb that uses little power. Contrary to the name, these bulbs are not in fact zero watts. The reason they are colloquially called "zero watt" bulbs is because when they were first made, they only had a power consumption rate of 15W but testing equipment at the time was unable to detect such low wattage causing people to think they didn't use any power. Todays "zero watt" bulbs are as little as 10W. +++ Hardly "zero watt" then. I wonder if the term was originally an advertising slogan as misleading as "zero carbon homes", because I cannot believe it was impossible to measure a power below 15W at the time these lamps were invented, even if indirectly from the Voltage and Current. (W = V x I ).
AC becomes zero at a certain instant of time but why do you get a continuous power supply?
The answer is you really don't. For example, a light bulb connected to AC really has no power at that instant of time when current is at zero. The filament in light bulb starts to turn off, but its residual heat keeps it glowing. In some fluorescent tubes you can actually see the 60 HZ "flicker". In an appliance like a TV the average power is maintained by various circuit components like capacitors that "save" up the electrons for use during the zero crossing of the current.
What would happen if one light bulb goes out in a parallel circuit?
Making the important assumption that each bulb is equal in electrical resistance, the current will increase proportionally to the number of bulbs added (until the current limit of the battery is reached, that is). Clarification ... The current through the bulbs that were already there doesn't change, but the newcomer-bulbs add to the total current from the battery or power supply.
How many amps in a low voltage light bulb?
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
Why we called zero bulb to zero volt bulb?
the zero bulb required less amount of electricty to glow the voltage of bulb is below 5 volt
If you have a thick wire attached to the positive terminal of a battery attached to a light bulb attached to a thin wire of the same length will the current be the same in both wires?
Yes; the current will be zero, because--as described--the wires are not connected in such a manner as to create a circuit.
How much was the light bulb in 1879?
Zero, nothing. It wasn't until 1880 that Edison patented the first commercially viable incandescent light bulb.
