1.	(i) The given figure shows a domestic electric circuit. Study this circuit carefully. List any two errors in the circuit and 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» Solution :(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`B_(2)` is not connected to the neutral wire. (c) Two SWITCHES `S_(1)and S_(2)`in both `B_(1)` circuit and no switch in bulb `B_(2)` circuit. (ii) Element of ELECTRIC heater-high melting point Element of fuse wire - low melting point (iii) (a) Each appliance has equal POTENTIAL difference. (b) Each appliance has separate switch to ON/OFF the flow of currentthrough it.
