A motor having an armature of resistance `2Omega` is designed to operate at `220 V` mains. At full speed, it devlops a back e.m.f. of `210V`. When the motor is running at full speed, the current in the armature is

A

`5A`

B

`105A`

C

`110A`

D

`215A`

Text Solution

Verified by Experts

The correct Answer is:
A
`i=(E-e)/(R )=(220-210)/(2)=(10)/(2)=5A`

A coil has an inductance of 0.7 H and is joined in series with a resistance of 220 Omega . When an alternating e.m.f of 220 V at 50 c.p.s. is applied to it, then the wattless component of the current in the circuit is

A fan operates at 200 volt (DC) consuming 1000W when running at full speed . It's internal wiring has resistance 1 Omega . When the fan runs at full speed , its speed becomes constant. This is because the torque due to magnetic field inside tha fan is balanced by the torque due to air resistance on the blades of the fan and torque due to friction between the fixed part and the shaft of the fan. The electrical power going into the fan is spent (i) in the internal resistance as heat, call it P_(1)(ii) in doing work against internal friction and air resistance producing heat, sound etc. call it P_(2) . When the coil of fan rotates, an emf is also induced in the coil. This opposes the external emf applied to snd the current into the fan. This emf is called back-emf,call it 'e' . Answer the following questions when the fan is running at full speed. The current flowing into the fan and the value of back emf e is

The armature of a generator of resistance 1Omega is rotated at its rated speed and produces 125 V without load and 115 V with full load. The current in the armature coil is
