The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is: 
The human nervous system is responsible for controlling and coordinating all the activities of the human body.
The Central Nervous System (CNS) comprises the brain and spinal cord.
