Understanding IOM's law and co-cores law is essential for analysing electrical circuits. IOM's law is a fundamental principle in electrical engineering that relates the current, voltage, and resistance in a circuit. IOM's law states that the current flowing through a load is directly proportional to the voltage across the load and inversely proportional to the resistance. By using IOM's law equation B equals IR, we can calculate the voltage, current, and resistance values in a circuit. In this exercise, you are given the values of voltage, B, and resistance, R, and need to calculate the current I using IOM's law. To suit the exercise, substitute the given values of B and it into the IOM's law equation B equals IR to find the current I. In this exercise, you are given the values of current, I, and resistance, R, and need to find the voltage, V, using IOM's law. To find the voltage, B, substitute the given values of I and it into the IOM's law equation B equals IR. Given the current, I, and voltage, V, this exercise requires you to calculate the resistance, R, using IOM's law. To find the resistance, R, divide the voltage, V, by the current I, using the equation R equals V, I, as per IOM's law.
