Answer:
Given that,
Resistance, Resistance
Voltage, V = 6V
(a) Total resistance,
(As they
are connected in series) (1)
(b) Total current, (1)
As lamp and conductor both are
connected in series, so current through both of them will be same as the total
current.
Current through each resistor =
0.25 A CD
(c) Potential drop across
resistor,
Potential drop across resistor,
(1)
The circuit diagram is shown
below
(1)
Or
(a) In electric motor,
electrical energy is converted into mechanical energy. (1)
(b) It works on principle that
when a current carrying conductor is placed in magnetic field, it experiences a
force. In other words we can say that when a rectangular coil is placed in a
magnetic field and current is passed through it, two equal and opposite forces
(on opposite side) act on the coil which rotates it continuously.
(1)
(c) The diagram of electric
motor is shown below
(2)
(d) Motors are used in electric
fans, pumps, grinders, mixers, etc. (1)
