1.	(i) The given figure shows a domestic electric circuit. Study this circuit carefully. List any two errors in the - circuit ind justify your answer(ii) Give one difference between the wires used in the element of an electric heater and in a fuse.(iii) List two advantages of parallel connection over series connection.
Answer» (i) Two errors are: (a) Fuse is incorrectly connected to the neutral wire (N), it must be connected to the live wire(L). (b) Bulb B2 is connected to the neutral wire. (c) Two switches S₁ and S₂ in both B₁ circuit and no switch in bulb B2 circuit. (ii) Element of electric heater-high melting point Element of fuse wire-Low melting point (iii) (a) Each application has equal potential difference. (b) Each appliance has separate switch to ON/OFF the flow of current through it.
