In the electrical circuit (ABC) as shown in the figure given below, the resistance R1, R2 and R3 are same and equal to 30 W. If a source of voltage 2V is connected across one arm, the current drawn from the voltage source is 2V + – B R2 R3 A R1

Electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules.
