Question

A bulb draws 0.1A current from a 220v
supply what current will this bulb draw
when it is connected to 110v.​

Answer 1

Answer:

Here, The bulb will draw out 0.05A of current when connected to a 110v supply.

Step-by-step explanation:

Here, As per our given question,

=Current drawn by the bulb when it is connected to 220v supply=0.1A

So, Resistance(R) of the bulb,

By applying Ohm's law, we get,

=V=I×R

=220=0.1×R

=R=220/0.1

=R=2200 ohms

Now, As we have the Resistance of the bulb,

So, Current drawn by the bulb when it is connected with a 110v supply,

=V=I×R (By ohm's law)

=110=I×2200

=I=110/2200

=I=0.05A

Hence, Now The bulb with draw 0.05A of current.

Thank you.
