Ohm's Law is a fundamental principle in electrical engineering that relates the current flowing through a conductor to the voltage across it and the resistance of the conductor.

• Ohm's Law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) across it and inversely proportional to the resistance (R) of the conductor.

• The formula for Ohm's Law is: V = I * R, where V is the vol...read more

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

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

• Current is the rate at which electric charge flows through a conductor.

• Other common units for current include milliamperes (mA) and microamperes (μA).

The voltage unit is measured in volts (V).

• The voltage unit is denoted by the symbol V.

• Voltage is the potential difference between two points in an electrical circuit.

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

Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes.

• Fermentation is a metabolic process that converts carbohydrates, such as sugars and starches, into alcohol or organic acids using microorganisms like yeast or bacteria.

• Common examples of fermentation include the production of beer, wine, yogurt, and bread.

• Fermentation is used in various industries such...read more

Safety relay is an electromechanical device that monitors the safety functions of a machine and stops it if a safety issue is detected.

• Safety relays are used to monitor safety functions such as emergency stops, guard doors, light curtains, etc.

• They work by using input signals from safety devices to determine if the machine is in a safe state.

• If a safety issue is detected, the safety relay will open its contacts and sto...read more
