Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

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

• For example, if a circuit has a vol...read more

Types of transformers include step-up, step-down, isolation, autotransformer, and distribution transformers.

• Step-up transformers increase voltage levels

• Step-down transformers decrease voltage levels

• Isolation transformers provide electrical isolation between circuits

• Autotransformers have a single winding with taps for different voltage levels

• Distribution transformers are used to supply power to residential and commercia

A capacitor is an electronic component that stores and releases electrical energy.

• Capacitors are used in electrical circuits to store energy and release it when needed

• They are commonly used in power supplies, motor starters, and electronic filters

• Capacitors are characterized by their capacitance, voltage rating, and tolerance

• Examples of capacitors include electrolytic capacitors, ceramic capacitors, and tantalum capaci

R. Y. B. stands for Red, Yellow, Blue - the three primary colors used in electrical wiring.

• R. Y. B. are the standard colors used for phase conductors in electrical wiring systems

• Red is typically used for the R phase, Yellow for the Y phase, and Blue for the B phase

• These colors help electricians easily identify and differentiate between the different phases
