Which position of a conducting retangular coil would result in
most induced current. WHen the coil is moving through the
field.
When the coil is halfway inside the magnetic field? or
when the coil is totally inside the magnetic field(very big
field). Note taht the motion is moving thro the field.
Quite obvious. More magnetic flux linkage cut = to more induced
current in the external circuit.
2) How does the ratings affect the real voltage.
A specific example: if the lamp in a parallel circuit has
ratings (24v 80w) while the battery is 12v. Whats the result of the
power and stuffs of the lamp. Whats the whole relationship.
I think Power is the more important factor here when deciding
how to connect. Current is the other important factor when
selecting a fuse. Voltage is just a in between link-connector.
Btw the above circuit doesn't work because
Emf of source = total p.d. of all components of the circuit
What is the work done in moving a box up a ramp. The height of
the ramp is 1.5m and the horizontal distance is 2m. The box is 500N
weight.
Length of ramp = Sq root 2^2 + 1.5^2 = 2.5
W=Fxd = 500x2.5 = 1250 J
4)Why cant work done be used to calculate net force?
Direction of force may not be the same as the direction of
motion, a.k.a. the force may not produce a motion in the same
direction as the force.
