Daniel,dextercioby said:How are the 2 lamps "added",in series,in parallel,mixed...?
As for the second,i think they mean 6W,thoough I'm not sure.
Daniel.
Ohm's Law is a fundamental law in physics that describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor.
Ohm's Law can be represented mathematically as V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms. This formula can be rearranged to solve for any of the three variables, depending on what information is known.
The unit of measurement for voltage is the volt (V). This unit is named after Italian physicist Alessandro Volta, who invented the first battery and discovered the concept of electric potential difference.
Ohm's Law can be used to calculate power in an electrical circuit. The formula for power is P = VI, where P is power in watts, V is voltage in volts, and I is current in amperes. This formula can also be rearranged to solve for any of the three variables.
Ohm's Law has numerous practical applications in the field of electrical engineering. It is used to design and analyze circuits, determine the appropriate components for a circuit, and troubleshoot electrical problems. It is also used in industries such as telecommunications, electronics, and power generation.
