Question

define current electric potential different and status ohms laws​

Answer 1

Answer:

Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.

Answer 2

Answer:

Electric current - Electric current is the rate of flow of electric charge.

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region.

Potential difference - difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other

=> If a positive charge is moved from a point at a higher potential to point at a lower potential energy is liberated.

=> In actual practice electric charge moves from lower potential to higher potential here there is a loss of energy by electrons moving from lower potential to higher potential the loss of energy appears as Heat.

State Ohm's law:

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R).

EXTRAS:

What is Ohm’s Law?

Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged. Mathematically it can be represented as,

Potential difference ∝ Current

V ∝ I

( When the value of V increases the value of I increases simultaneously)

Formula of Ohm's law:

V = IR

Where,

V is Voltage in volts (V)

R is Resistance in ohm (Ω)

I is Current in Ampere (A)

applications of Ohm’s law are:

=> To determine the voltage, resistance or current of an electric circuit.

=> Ohm’s law is used to maintain the desired voltage drop across the electronic components.

=> Ohm’s law is also used in dc ammeter and other dc shunts to divert the current.
