Magnetic effect
Luminous effect
Thermal effect
Chemical effect
Answer is Right!
Answer is Wrong!
The correct answer is: All of the above.
Electric current passing through a circuit can produce a magnetic effect, a luminous effect, a thermal effect, and a chemical effect.
- Magnetic effect: When an electric current passes through a conductor, it creates a magnetic field around the conductor. This magnetic field can be used to create electromagnets, which are used in many devices, such as motors, generators, and loudspeakers.
- Luminous effect: When an electric current passes through a gas, it can cause the gas to emit light. This is the principle behind light bulbs and neon signs.
- Thermal effect: When an electric current passes through a conductor, it causes the conductor to heat up. This is the principle behind electric heaters and stoves.
- Chemical effect: When an electric current passes through a solution, it can cause the solution to react. This is the principle behind electrolysis, which is used to separate metals from ores and to produce chemicals such as chlorine and sodium hydroxide.
