Question

How much current will an electric heater draw from a 220V source if the resistance of the bulb is 1200 ohm?If in place of bulb of resistance 100 ohm is connected to the sources,calculate the current drawn by it?
Friends it is 2mark question

Answer 1

Answer:

Answer: Current drawn by the bulb = 0.183 Amperes.

Explanation:

V=220v

R=1200ohm

I=?

I=V/R

I=220/1200

11/60Ampere

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

When heater of R=100ohm

V=220v

R=100ohm

I=?

I=V/R

I=220/100

I=2.2Ampere

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

Hope this helps
