Some of the questions and their solutions from NCERT Solutions for Class 10: Electricity, are as follows:
Q. What does an electric circuit mean?
Sol. An electric circuit consists of electric devices, switching devices, etc. These things are connected by conducting wires.
Q. Define the unit of current.
Sol. The unit of electric current is ampere (A). 1 A is defined as the flow of 1 C of charge through a wire in 1 s.
Q. What is meant by saying that the potential difference between two points is 1 V?
Sol. If 1J of work is required to move a charge of amount 1C from one point to another, then it is said that the potential difference between the two points is 1V.
Q. Why does the cord of an electric heater not glow while the heating element does?
Sol. The heating element of an electric heater is a resistor. Heat produced by it is directly proportional to its resistance. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes too hot and glows red. On the other hand, the resistance of the cord is low. It does not become red when current flows through it.
