it is clear that volts equal to the current as per ohms law.
is it appliable to the AC power or only for DC. if it is
appliacable to AC in transformers when voltage increases
the voltage decreases ????? why??????????????
Answer Posted / javed
ohm law is applicable for both ac and dc
according to ohm law if we pass current through any
resistive ckt, the ratio of change in current directly
proportional to change in voltage
V = I*R (where R is constant)
but in case of inductive ckt (like transformer), inductance
of the ckt always try to oppose the change in current, but
in case of dc inductance of the ckt is zero, so in case of
AC, voltage vary nonlinerly with change in current.
(remember ohm law in not applicable for inductive ckt it is
only applicable for resistive ckt)
