Question

A bulb of resistance 484 ohm is connected to 220v line.how much current will this bulb draw

Answer 1

apply ohms law
V=IR
220 = I × 484
or
I = 220/484
I= 0.45 ampere

Answer 2

✰ Given -

• Resistance (r) = 484 Ohm
• Voltage (v) = 220 volt

✰ To Find -

• Current (I) = ?

✰ Solution -

We know Ohm's Formula,

$✓ \: </strong><strong>V</strong><strong> = </strong><strong>I</strong><strong> \times </strong><strong>R</strong><strong>$

Placing Values,

$⟶220 = I \times 484$

$⟶I = \frac{\cancel{220}}{\cancel{484}}$

$⟶I = 0.454Ampere$

⛬ Current is 0.454 Ampere
