Will the current in the light bulb connected to a 220v source be greater or less than when the same bulb is connected to a 110v source?
A: The current is not a function of voltage available but rather the power needed to light the lamp. To answer your question a 100 watts lamp will require 1.83 times more current for a lamp rated as 100 watts at 120 volts.
It is a basic ratio 220:120
AnswerI disagree with the previous answer. The power rating of a lamp only applies when the lamp is subject to its rated voltage -which is why both values are shown on the lamp (e.g. 60 W / 120 V).
So, if you subject a lamp to less than its rated voltage, it will not achieve its rated power. In fact, the decrease in power will be significantly greater than the corresponding decease in voltage. It will certainly not 'compensate' by drawing more current!
However, to directly answer your question, the current drawn by a lamp connected to a 220-V supply will indeed be greater than the current drawn by the same lamp connected to a 110-V supply.
What else can I help you with?
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
Are the lights in your school connected in series current or parallel current?
Overhead lights are typically connected in parallel. If they were connected in series, then, if one light went out, all of the lights would go out. Think of Christmas lights, they are connected in series. When one of the lights burns out, the whole string of lights goes out.
How does a flashlight work?
A flashlight has a power source (usually ordinary batteries), a light source of some sort (a light bulb or LED, for example), and some electrical wiring to connect them, with a switch to turn it on and off. The power source makes the light source give off light.

Will the current in a light bulb connected to a 200-v source be greater or less than when the same bulb is connected to a 110-v circuit?
The current in the light bulb will be greater when connected to the 200-v source compared to the 110-v circuit, assuming the resistance of the light bulb remains constant. This is because current is directly proportional to voltage in an electrical circuit according to Ohm's Law (I = V/R), so a higher voltage will result in a greater current flow through the bulb.
What is the difference between light switch load and line connections in a circuit?
In a circuit, the line connection carries the electrical current from the power source to the light switch, while the load connection carries the current from the light switch to the light fixture. The line connection is typically connected to the hot wire, while the load connection is connected to the wire that leads to the light fixture.
How must the light bulb be connected in order for it to light up?
The light bulb must be connected in a closed circuit with a power source, such as a battery or electrical outlet, for it to light up. This means that the positive terminal of the power source must be connected to the positive terminal of the light bulb, and the negative terminal of the power source must be connected to the negative terminal of the light bulb. This allows the flow of electricity to power the light bulb and make it light up.
Why does a bulb in a circuit not work?
A light bulb is not lit when the swtich is not connected to the wire becasue there is no flow of electricity, specifically, flow of electrons. By disconnecting the wire, the bulb is no longer connected to the electricity source.
What do you use to make a amp or light fitting light up?
A lamp or light fitting will light up if connected to either Alternating Current (AC), or Direct Current (DC). AC is from the mains, and DC is from a battery. So it depends on the construction and components used to construct the lamp as to which electrical source you use.
How does the current in a light bulb connected to a 400 V source compare to the current when this light bulb is connected to a 60 V source?
Let's examine what it means when a bulb is 100W rather than 60W. I'm assuming that you meant to state that they are 120V bulbs being connected to a 240V circuit1. With the same voltage on each, and because power is voltage times current, the current must be greater in a 100W bulb than in a 60W bulb. Since a incandescent bulb is a linear load, if you double the voltage then you double the current2. So the current through the 100W bulb is still greater than through the 60W bulb. Or you may analyze it a bit more. With both on 120V, for more current to flow in the 100W bulb, the resistance of it must be less than that of the 60W bulb. So you may generalize that under any voltage (same voltage applied to each), the 100W bulb will always have more current through it than the 60W bulb. 1Actually, if they are 120V bulbs in a 240V circuit, there is a high probability that they will blow out. But before they do, this is what will happen. 2Well, slightly less than double, because the temperature coefficient on the filament is positive, so the hotter it is, the greater the resistance. Although this may seem nonlinear, a light bulb or other temperature sensitive resistive element is still defined as linear if over the short term it obeys Ohms law at any instant of the waveform. The current in the 100 watt bulb will be greater. Power is current times voltage, so current is power divided by voltage. Voltage is the same is both cases of this question, so current is proportional to power at 240V.
What determines the brightness of light?
The brightness of light is determined by the intensity of the light source, which is the amount of light energy emitted per unit of time. The greater the intensity of the light source, the brighter the light will appear.
What is a simple wiring diagram for a light switch?
A simple wiring diagram for a light switch involves connecting the power source to the switch, and then connecting the switch to the light fixture. The power source is typically connected to the switch through a black wire, and the switch is connected to the light fixture through a white wire. A ground wire is also connected for safety.

Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
Why resistors are connected parallel with current source?
The can be connected in parallel, in series, or in some combination. Household appliances are connected in parallel, because that way:1. Each appliance receives the full voltage. Results are thus more predictable. For example, a light bulb will give the same light, no matter whether it is the only light bulb, or whether others are also connected.2. Each appliance will continue working even if the others are switched off.
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
