FAQs on Maharashtra Board Class 10 Solutions for Science Chapter 4 Effects of Electric Current - PDF
1. What is the heating effect of electric current?
A resistor, when connected to an electric circuit, produces heat in the circuit, which is due to the heating effect of the electric current. Equipment such as water heater, electric cooker, etc., works due to this property of electric current.
2. Mention some common appliances where the electric motor is used.
The electric motor is used in day-to-day appliances such as hair dryers, washing machines, blenders, mixers, etc.
3. What can the galvanometer measure?
A galvanometer is able to measure current in an ammeter and potential difference in a voltmeter.
4. Mention the law of induction.
When there is a change in the magnetic lines of force that are passing through a coil, there will be a current induced in the coil.
5. Which metal is used to create a solenoid-like coil in the electric bulb?
Tungsten is the metal that is used to create the coil in an electric light bulb since it has a high melting point and high resistance.
