Answer:
(a)
Let the resistance of the lamp
Resistance of conductor
Total resistance in series,
Current Voltage (V) = 10 V
Using
Ohm's law, V= IR
(b) Now, a resistance of is
connected in parallel with the series combination. Therefore, the total resistance
of the circuit is given by
Hence, current flowing in the circuit,
Thus, 1 A current will flow through resistor and 1 A will flow through
the lamp and conductor of resistance.
Hence, there will be no change in current flowing through . conductor. Also, there will be no
change in potential difference across the lamp.
