Cauvery Steels Interview Questions, Process, and Tips

Current is the flow of electric charge in a circuit.

• Current is measured in amperes (A).

• It is caused by the movement of electrons or other charged particles.

• Current can flow in both directions in an alternating current (AC) circuit.

• In a direct current (DC) circuit, current flows in only one direction.

• Current is essential for the operation of electrical devices and is controlled by voltage and resistance.

• Examples of curr...read more

A power unit is a measurement of the rate at which work is done or energy is transferred.

• Power unit is a unit of measurement for power.

• It is used to quantify the rate at which work is done or energy is transferred.

• The most common power unit is the watt (W), which represents one joule of energy per second.

• Other power units include horsepower (hp) and kilowatt (kW).

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

• The current unit is used to quantify the rate of flow of electric charge.

• It is named after the French physicist André-Marie Ampère.

• The symbol for the ampere is 'A'.

• Current can be either direct current (DC) or alternating current (AC).

• Examples of current units include milliamperes (mA) and kiloamperes (kA).

The voltage unit is a measurement of electrical potential difference.

• Voltage unit is used to measure the amount of electrical potential difference between two points in a circuit.

• The SI unit for voltage is the volt (V).

• Other common voltage units include millivolts (mV), kilovolts (kV), and megavolts (MV).

• Voltage can be measured using a voltmeter or multimeter.

• For example, a typical household electrical outlet in the Un

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.

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

• It helps in understanding the relationship between voltage, current, and resistance in an electrical circuit.

• Ohm's Law can be used to calculate any one o...read more
