The current unit is the ampere (A), which measures the flow of electric charge.

• The unit of electric current is the ampere (A).

• Current is the rate of flow of electric charge.

• It is measured using an ammeter.

• One ampere is equal to one coulomb of charge passing through a point in one second.

Voltage is the unit of measurement for electric potential difference.

• Voltage is the force that pushes electric charges through a circuit.

• It is measured in volts (V).

• Voltage is essential for the operation of electrical devices.

• Examples of voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it.

• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• The current symbol is represented by the letter 'I'.

• Ohm's law is fundamental in understanding and analyzing electrical circuits.

• Example: If a circuit has a voltage of 12 volts and a resistance of 4 o...read more

The two types of winding in electrical engineering are lap winding and wave winding.

• Lap winding is used in DC machines and is characterized by multiple parallel paths for current flow.

• Wave winding is used in AC machines and is characterized by a single path for current flow.

• Lap winding provides high current capacity and low voltage output, while wave winding provides low current capacity and high voltage output.

• In lap ...read more

The primary winding is the first coil in a transformer that receives electrical energy.

• The primary winding is typically connected to the power source.
