CURRENT ELECTRICITY |Problems on Combination of Resistors |JEE| 12 Physics | 9 PM By Sachin Sir | L4

Electrical current is the flow of charged particles. The electric current flows through a wire the same way as how water moves in a river. The electricity is nothing but the flow of electrons. There are two main combinations of resistors in circuit, that is series and parallel. In the given table, Column I shows different combinations of resistors, Column II shows voltages of different arrangements of resistors and Column III shows currents and voltage division needed or not in different arrangements of resistors. When does the current division problem arise?

Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistance of 2 Omega in series with a combination of two resistors ( 4 Omega each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2 Omega resistor be the same as that across the parallel combination of 4 Omega resistors ? Give reason.
