Question

calculate the charge passing through an electric bulb in 20 min if the value of current is 200ma??

Answer 1

20mins= 1200s
200mA= 0.2A

I= Q/T
Q=I×T= 1200×0.2=240C

Answer 2

Answer:

The charge passing through an electric bulb is 4 coulomb.

Step-by-step explanation:

Given : An electric bulb in 20 min if the value of current is 200 ma.

To find : Calculate the charge passing through an electric bulb?

Solution :

The formula which shows the relationship between current, time and charge is

$I=\frac{Q}{T}$

Where, I is the current is 200 mA

Convert mA into A

1 A = 1000 mA

1 mA=0.001 A

200 mA= 0.2 A

I=0.2 A

T is the time = 20 min

Q is the charge in coulomb

Substitute all the values in the formula,

$0.2=\frac{Q}{20}$

$Q=0.2\times 20$

$Q=4$

Therefore, The charge passing through an electric bulb is 4 coulomb.
