Question

how much current does electric heater drawn from 220v line , of the resistance of heater is 5 ohm​

Answer 1

Solution :

➡ Given:

✏ Potential difference across electric heater = 220 V

✏ Resistance of heater = 5$\Omega$

➡ To Find:

✏ Current drawn by electric heater.

➡ Concept:

✏ As per ohm's law current passing through a conductor is directly proportional to the potential differece.

➡ Formula:

$\mapsto \rm \: V \propto \: I \\ \\ \mapsto \underlind{\boxed{\bold{\rm{\pink{V=I \times R}}}}}$

➡ Terms indication:

✏ V denotes potential difference.

✏ I denotes current.

✏ R denotes resistance of material.

➡ Calculation:

$\mapsto \rm \: I = \frac{V}{R} = \frac{220}{5} \\ \\ \mapsto \: \boxed{\red{\rm{I=44\:A}}}}}$
