Answer a,b,c,d,e questions
Answers
Answer:
a)The above diagram shows the construction of an ELECTRIC MOTOR
b)This equipment work on FLEMING LEFT HAND RULE
c)The coil ABCD rotates in ANTICLOCKWISE DIRECTION
d) Fleming's left hand rule
● Fleming's left hand rule is used to find the direction of the force on the conductor
● according to this rule the left hand thumb index finger in the middle finger stretch so as to be perpendicular to each other if the index finger is in the direction of the magnetic field in the middle finger points in the direction of the current then the direction of thumb is the direction of the force on the conductor
e)In household articles such as washing machines, refrigerators, coolers, dish washing machines, ceiling fans, exhaust fans, table fans etc, electric motors are very widely used. Small, micro electric motors are used in a wide scale in electronic instruments, computers, space applications like satellites etc.
plz mark me as BRAINLIEST
Answer:
a-electric motor
b-it works on the principle that whenever a coil is kept in a magnetic field it experiences a magnetic force due to which the coil rotates
c-Flemming left hand rule
d- according to this rule stretch your left hand such that the forefinger,middlefinger and thumb are mutually perpendicular to each other , if forefinger indicates the direction of magnetic force,middle finger indicates the direction of current then thumb will give you the direction of force acting
e -used in fans , mixer grinder, washing machine
