Will heating effect be different from direct and alternating currents?

Through a pure resistance, AC and DC have the same effect. In fact, an effective description of “the RMS voltage” for an AC voltage is that voltages which produces the same heating as the same voltage of DC.

Does the resistor behave differently when used in a DC or an AC circuit?

The resistance value of the resistor in both AC and DC circuits is same irrespective of the frequency of the AC supply voltage. The change in direction of current in AC supply does not affect resistors behavior.

What is the difference between DC and AC electricity?

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

When AC is connected to a resistor What is the phase difference between the current and voltage?

The phase difference between current and voltage in an AC circuit is 4Π​ radian.

How is AC circuit different from DC circuit?

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

Why is AC more efficient than DC?

AC is relatively much easier to transmit over long distances then DC. As AC allows for it to be stepped up or stepped down to higher voltages by the use of the Transformers. This property allows for transmitting of power over power lines over long distances without much loss of energy.

Why does AC wire heat up faster than DC?

This will cause slightly more ohmic heating in AC than in DC. That’s why AC wire is usually stranded while DC wire is usually solid — more strands = more surface area. Share Cite Follow edited Aug 4 ’14 at 22:00

Why is the resistance of a DC wire lower than AC?

That’s why the resistance offered by a wire is lower for DC than AC as will as AC lines need more insulation than DC. In DC Circuits, we calculate the resistance by Ohm’s Law.

What is the difference between AC current and DC current?

DC current will travel through the entirety of the wire — AC current will tend to move on the outside of the conductor (see Skin Effect). This will cause slightly more ohmic heating in AC than in DC. That’s why AC wire is usually stranded while DC wire is usually solid — more strands = more surface area.

How do you find the resistance of an AC circuit?

R = V/I. Good to Know: When solving electric circuits for finding resistance and you are not sure which one should you take into account whether AC or DC resistances, then, if the current passed is AC, then take AC resistance else if the current passed is DC, take DC resistance.
