ELECTRIC CURRENT
103. An
electric lamp whose
resistance is 10 Ω
and
conductor of 5 Ω
resistance are connected
to
a 10 V battery
calculate
[a]
the total resistance of circuit
.
[b]
the current through the circuit
[c]
the potential difference across
the electric
lamp
an conductor .
104. An electric lamp
whose resistance is 18 Ω
and
conductor of 8 Ω
resistance are connected
to
a 12 V battery
calculate
[a]
the total resistance of circuit
.
[b]
the current through the circuit
[c] the potential difference
across the electric
lamp
an conductor .
105. An electric lamp
whose resistance is 30 Ω
and
conductor of 12 Ω resistance
are connected
to
a 30 V battery
calculate
[a]
the total resistance of circuit
.
[b]
the current through the circuit
[c] the potential difference
across the electric
lamp

106. Two resistance
A and B 50
Ω and 10 Ω
when connected in parallel
later on its series .
the total voltage is 20 V.
In which arrangement
will be
voltage across A and B be
same and
in which case will
the current flowing through
A
and B be
same ?
