What is ohms law? can u explain it in simple terms?
Answer:
Ohm's law states that, in an electrical circuit, the current passing through a conductor from one terminal point on the conductor to another terminal point on the conductor is directly proportional to the potential difference (i.e. voltage drop or voltage) across the two terminal points, and inversely proportional to the resistance of the conductor between the two terminal points. In mathematical terms, this is written as:
I = V/R
where I is the current, V is the potential difference, and R is a constant called the resistance. The potential difference is also known as the voltage drop, and is sometimes denoted by E or U instead of V.
It is like saying the pressure (voltage) at the end of a hose is what it takes to move a certain amount of water (current) through a certain size of hose (resistance)
Well!
ohm's law means the voltage(V) will increase if you increase the current(I), also the voltage(V) will increase if you increase the Resistant(R) i.e V=IR.
The potential difference is directly propotional to the current & the resistant.The law stating that the direct current flowing in a conductor is directly proportional to the potential difference between its ends. It is usually formulated as V = IR, where V is the potential difference, or voltage, I is the current, and R is the resistance of the conductor
Ohms law is the rate of flow of the current that is equal to electromotive force divided by pressure.
Volts=E force
Current =I amps
Resistance=R ohms
In a closed Electrical Circuit, the amount of current is depends
on potential difference available and resisitance. Ohm's law
states that
I = V/R
where I is the current measured in Amperes
V is the potential difference applied across the circuit measued in Volts
and R is the resistance measured across the circuit.
