### NCERT Solutions for Class 10 Science Chapter 12: Points to Remember

The important points to remember make it easier for the students to prepare for the exam. These are easily available on Embibe. Below mentioned are some of the important points to be remembered from NCERT Solutions for Class 10 Science Chapter 12 to score good marks in the exams:

• Current
(i) Current through a given area of a conductor is the net charge passing per unit time through the area.
(ii) SI unit of current is ampere and it is a scalar quantity.
• Electromotive force:
The work done per unit charge by the source in taking the charge from lower to higher potential energy is called the source’s electromotive force, or emf.
• Ohm’s law:
(i) Ohm’s law: The electric current I flowing through a substance is proportional to the voltage V across its ends, i.e., VI or V=RI, where R is called the resistance of the substance. The SI unit of resistance is ohm(Ω).
• Temperature coefficient of resistivity:
In the temperature range in which resistivity increases linearly with temperature, the temperature coefficient of resistivity is defined as the fractional increase in resistivity per unit increase in temperature.
• Kirchhoff’s law:
(i) Kirchhoff’s junction Rule: At any junction of circuit elements, the sum of currents entering the junction must be equal the sum of currents leaving it.
(ii) Kirchhoff’s Loop Rule: The algebraic sum of changes in potential around any closed loop must be zero.
•  Potentiometer:
(i) A potentiometer is a linear conductor of uniform cross-section with a steady current set up in it. This maintains a uniform potential gradient along the length of the wire. Any potential difference which is less than the potential difference maintained across the potentiometer wire can be measured.
