Why is it impossible to use a transformer on a direct current where the current is steady at all times?
alternating current has two halfs in one cycle.In one half it flows in one direction and in other half it flows in opposite direction.due to fluctuations ,alternating current has ability to produce phenomenon of mutual induction. and mutual induction is the basic principle on which a transformer works while direct current cannot produce phenomenon of mutual induction.thats why a transformer is not used on a direct current
What else can I help you with?
Can a constant dc current can induce a steady state voltage in a transformer?
No, the current has to change for a voltage to be induced in the transformer.
Can a constant dc current induce a steady state voltage in a transformer?
No. A constant DC current of sufficient magnitude induces smoke in a transformer.
What type of current has steady potential difference across a circuit?
That would be DC or Direct Current.
What is the behavior of the current through a capacitor in steady state?
In steady state, the current through a capacitor is zero because the capacitor blocks the flow of direct current (DC) once it is fully charged.
How can identify AC and DC?
DC is direct current, and is characterized by its steady flow of current. AC is alternating current. It is characterized by increases and decreases in the current.
What is the definition of direct current?
(a) A current flowing in one direction only; -- distinguished from alternating current. When steady and not pulsating a direct current is often called a continuous current. (b) A direct induced current, or momentary current of the same direction as the inducing current, produced by stopping or removing the latter; also, a similar current produced by removal of a magnet.
Why dc current cannot be used in transformers?
Transformer are passive devices thattransform AC to AC by magnetics and coupling. DC IS UNIDIRECTIONAL it does not change POLARITY. While it is possible to saturate a transformer primary it output cannot reflect the change since it has reached steady state
What is the relation of ac and DC?
DC is direct current, a steady current supplied from a steady voltage. AC is alternating current changing like a sine-wave positive and negative, with the advantage that it can be changed by transformers. DC can be derived from AC by rectification and smoothing circuits, which are built into equipments which draw their power (AC) from public electricity suppliers.
Alternating current can be changed to direct current by?
using a rectifier, which converts the AC signal into a pulsating DC signal, and then using a filter to smooth out the pulsations in the signal, resulting in a steady DC output.
Steady flow of electrons?
elelctric current
What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
What is a direct currnet?
Direct current is a flow of electricity which only goes one way. Batteries, for example, produce direct current, so the current must flow all the way through a circuit and back into the battery to work. Alternating current is what comes out of a wall outlet, and it alternates in both directions, with current flowing in and out of the outlet.
