Answer / arvind
Yes it is possible,if two coils have same resistance but
supplied voltage is different as 75 v for 3 A and 150 v
supply for 6 a coil. from ohm's law.

Answer / man
even when applied voltage to both the coils are same we can
have different currents.as because the inductance of both
the coils can be different(since its single phase supply so
inductance will come into picture,which depends on the
dimension of the coils),so the impedance of the coils will
be different and hence currents will be different even for
same voltage.

Answer / mohseen ahmed
according to ohms law V=IR......if voltage is contant then
there will b constant current following through
resistance..but if supply voltage is not constant then load
current may b different....i hope u got the answer...REGARDS

The coil wound over an insulted iron former will draw less
current.

Answer / noel c. tigas
Answer # 3 is incorrect. We need to analyse the statement.
Heating coils are surely resistive, hence, we can eliminate
inductance. Answer no.#1 is the correct answer. They
should have different power ratings; hence, their operating
voltage, also the formula P = Square of I x R.
