Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
Why do we use AC supply in our homes?
The power transmission would require bigger wires to transmit high dc current so instead high voltage ac current is transmitted through long distance linesTo reduce losses it is necessary for the value of current through lines to be lowTranformers donot work for dc current so one cant step up and step down dc current voltage like it can be done with ac current
Why is not impractical to power distribution in power DC?
IN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTIN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTAnswerThe main reason is that we cannot use transformers to easily and efficiently change the magnitude of DC voltages, and the ability to change voltages is essential for electricity distribution. However, having said that, very high-voltage transmission over exceptionally long distances is often done using DC. This is because DC losses are far lower than AC losses.
Is wave energy an AC or DC current?
mainly AC but can be DC if done correctly
What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.
Why D.C. current is not passed from our body?
Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
Why you use ac current of home instead of dc?
alternating current is generally instantaneous in nature and even in transmission lines it is easy to transmit with less losses when compared to dc as because it possess frequency where as dc do not have
Why ac prepared DC current?
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered
What is charged by having a one way current flow through it?
A battery is charged by having a DC current flow through it.
What is the effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
