Which effect of current is utilised in the working of an electric fuse?

The heating effect is used. Normally the current flows through the fuse without undue heating. But if too much current passes through, the fuse will heat and melt, thus stopping the current which could cause a fire if it was not stopped .

What effect does the pencil lead have on the brightness of the bulb in a circuit?

The pencil lead does not have a significant effect on the brightness of the bulb in a circuit because it does not conduct electricity efficiently. In order for the bulb to light up brightly, the circuit needs an efficient conductor such as a metal wire to allow the current to flow easily and light up the bulb.


What is luminous effect of electric current?

The luminous effect of electric current refers to the production of light when an electric current passes through a material that emits light, such as an incandescent light bulb or a phosphorescent material. This process involves the conversion of electrical energy into light energy.


How do you know when electric current is flowing in a light bulb circuit?

You know if current is flowing in a bulb circuit because, if there is enough power (voltage times current), the bulb will illuminate. If there is current, but not enough power to illuminate the bulb, you will need to measure the current with an ammeter to see if there is any current.


Does the thickness or the length of the wire effect the brightness of the bulb?

The thickness of the wire (resistance) and length of the wire can affect the brightness of the bulb. Thicker wire has less resistance, allowing more current to flow and producing a brighter bulb. Shorter wire lengths also reduce resistance, resulting in a brighter bulb due to more current flowing through it.


Do any conductor have a different effect on a ligh bulb than others?

Yes, different conductors can have varying effects on a light bulb. Conductors with higher electrical conductivity will allow more current to flow, resulting in the light bulb glowing brighter. Conversely, poor conductors will restrict current flow, causing the light bulb to be dimmer or not light up at all.


Watt is the current allowed to flow through a bulb?

The current flowing through a bulb is equal to the (voltage across the bulb) divided by the (bulb resistance), and can be expressed in Amperes. The rate at which the bulb dissipates energy is equal to (voltage across the bulb) times (current through the bulb), and can be expressed in watts.


What happens to a light bulb when put in series with a inductor?

When you put a light bulb in series with a inductor, the inductive reactance of the inductor reduces the current available to the light bulb, making it less bright. For this effect to be noticed, however, you need a very large inductor. To cut the current in a 60W bulb at 120VAC/60Hz by one half, for instance, you need an inductor around 0.6 henrys.


What can be inferred about the current passing through the bulb?

The current passing through the bulb is directly related to the voltage applied across it and the resistance of the bulb. Using Ohm's Law (I = V/R), we can calculate the current flowing through the bulb by knowing the voltage and resistance values. Additionally, the brightness of the bulb can also be an indicator of the current passing through it, as higher current typically results in a brighter bulb.


What is the connection of the reading of a ammeter and the brightness of the bulb?

If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.


How does a capacitor supply current to a bulb?

A capacitor supplies current to a bulb by storing and releasing electrical energy in the form of charges. When the capacitor is connected to the bulb, it discharges its stored energy, providing a temporary flow of current to power the bulb.
