Question

An electric water heater draws 10 A of current from a 240-V power line.. What is its resistance? With solution

Answer 1

GIVEN :-

• voltage of electric heater = 10 A.
• Current = 240 V.

TO FIND :-

• The resistance.

SOLUTION :-

By using Ohm's Law,

⇒ V = IR.

• V → voltage.
• I → current.
• R → resistance.

⇒ R = I/V

⇒ R = 240/10

⇒ R = 24 Ω.

Hence the required value of resistance 24 ohm.

______________…

Ohm's Law,

★ V = IR.

Ohm's law was invented by great German physicist "Georg simon ohm in 6 july 1854. Ohm's law states that current flowing through a conductor is directly proportional to the voltage (I ∝ v) and inversely proportional to the resistance ( I ∝ 1/R).
