Question

How much current will an electric bulb draw from a 220V source, if the resistance of the bulb filament is 1200Ω??...How much current will an electric heater coil draw from a 220V source if the resistance of the heater coil is 100Ω.??!


Pls help to find....✔️✔️

Answer 1

Good morning!!!!

⭐Hey here is your answer ⭐

Given !!...

✔️✔️For the first Part.......

V = 220V

R = 1200 Ω

We have to find .... Current (I)


I = V/R

I = 220V/1200Ω

I = 0.18A.........

Thuerefore, Current is equal to 0.18A......


✔️✔️For second part ......

Given !!!

V = 220V

R = 100Ω


I = V /R

I = 220V/100Ω

I = 2.2 A...

Therefore the current. Will be 2.2A...☺️



I HOPE IT WILL HELP YOU ☺️✌️

Answer 2

Hey friends!!

-----------------------------------------------------

Here is your answer↓

-----------------------------------------------------

=> First question:-

=> It is given that:-
→ Voltage= 220V.

→ Resistance= 1200Ω.

→ Current=?¿

=> Current (I)= Voltage (V)/ Resistance (R).

=> I = 220V/1200Ω.

=> I = 11/60A.
OR
→ I = 0.183 A.

=> Second question:-

=> It is given that:-
→ Voltage= 220V.

→ Resistance= 100Ω.

→ Current=?¿

=> I = V/R.

=> I = 220V/100Ω.

=> I = 22/10A.
OR
→ I = 2.2 A.

Thanks .
