Question

Define ohms law and it's formula derivation for 5marks

Answer 1

Ohm's Law is the mathematical relationship among electric current,resistance, and voltage. The principle is named after the German scientist Georg Simon Ohm. ... If a DC power source providing E volts is placed across a resistance of R ohms, then the current through the resistance is equal to E/R amperes

Answer 2

ohms law states that if the physical condition of a conductor remain constant (temperature ,length area of cross section ) then the potential difference across the conductor will be directly proportional to the current flowing across it ......i.e mathematically V directly proportional to the I and to remove the proportional sign we use a constant and in this we use R (resistance) as a constant so it will be V=IR.....
