When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects .
What are the 2 main types of current?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC) . With direct current, electrons move in one direction.
What are the two effects of current?
Answer: The two effects of electric current are; heating effect and magnetic effect .
What are the three effect of current?
When an electric current flows in a circuit it can have one or more of the following three effects: heating, magnetic or chemical .
What are the two effect produced by electric current?
The two effects of electric current are: Heating effect of electric current . Magnetic effect of electric current .
What is Joule’s law of heating Class 10?
Joule’s Law states that H (Heat) = I (Current) x V (Voltage) x T (Time the current is allowed to flow) . Or, written differently, H (Heat) = I2 (Current squared) x R (Resistance) x T (Time the current is allowed to flow). ... Joule’s Law is an equation that gives the amount of heat (energy) delivered to something.
In what way heat depends on current?
When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor . A higher resistance produces more heat.
Why do we have 2 types of current?
There are two different types of current in widespread use today. ... In a direct current, the electrons flow in one direction . Batteries create a direct current because the electrons always flow from the ‘negative’ side to the ‘positive’ side. In a direct current, the electrons travel in one direction.
Which type of current is used in homes?
Alternating current (AC) electricity is the category of electricity usually used in homes and businesses. Direct current (DC) means the unidirectional stream of electric charge. Most of the digital electronics use DC.
What is current formula?
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R . The SI unit of current is Ampere (Amp).
What’s the effect of current?
| Electric current (contact for 1s) Effect | 50 to 150 mA Extreme pain . Respiratory arrest. Muscles reactions. Possible Death. | 1 to 4.3 A Fibrillation of the heart. Muscular contraction and nerve damage occur. Likely death. | 10 A Cardiac arrest, severe burns. Death is probable |

What are the 5 effects of electric current?
The main effects are heating, chemical and magnetic effects . When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.
Which effect of current causes the bulb to glow?
Therefore, the effect of current responsible for the glow of the bulb in an electric circuit is the heating effect . So, the correct answer is “Option B”. Note: Due to the moving electrons in the filament of the bulb, a magnetic field is also produced resulting in some magnetic effects.
What are the two effects of atmospheric refraction?
(a) The twinkling of stars is produced by atmospheric refraction. (b) Advanced sunrise and delayed sunset are also effects produced by atmospheric refraction.
Which effect of electric current is Utilised?
The heating effect of current is utilised in the working of an electric fuse.
What is an example of the heating effects of electricity?
This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called the heating effect of current. Example, Electric iron, electric toaster, water heaters, etc. , work on this effect.
