. State and explain Ohms law
Through a resistor, current is directly proportional to voltage loss. For example, if the current doubles, the voltage doubles as well. A voltage must be applied across a resistance in order for current to flow through it. The relationship between voltage (V), current (I), and resistance (R) is given by Ohm's Law.
Ohm’s law states that if the temperature and other physical variables remain constant, the electric current flowing through a conductor is directly proportional to the potential difference across its ends.
