What is the law of cross-sectional area for resistance? At constant temperature, if the length of a conductor is kept constant then the resistance of that conductor is proportional to the cross-sectional area of that conductor.
What is a galvanometer? The device used to check the presence of electric flow is called a galvanometer.
What is the series connection of resistors? If two or more resistors are connected one after another then the connection is a series connection.
What is the unit of specific resistance? The unit of specific resistance is Ωm (Ohm-meter)
What is the unit of resistance? The unit of resistance is Ohm.
What is the dimension of resistance? The dimension of resistance is ML2T-3I-2.
What does conductivity depend on? Conductivity depends on the temperature and element of the conductor.
What is the parallel connection of resistors? If two or more resistors are connected in such a way that one terminal of all the resistors are common in one point and also the other terminal of the resistors are common in another point, then the connection is called the parallel connection of resistors.
