Question

what current flows through a bulb if 360 C of charge moves through a bulb in 20 minutes

Answer 1

Q=it then I=Q/t……then we have value of Q and time t… But we convert minutes to second then 10 minute =60×10=600 seconds.. Now put the value of Q and t and get the value of current.. I=300/600=0.5amp

Answer 2

The value of the current will be 0.3amp

Given:

Charge measured = 360C

Time = 20 minutes

To find:

The current flow

Solution:

Since the time is given in 20 minutes.

Converting it to seconds

1 minute = 60 seconds

Therefore,

20 mins = 60 × 20

= 1200 seconds

Using the formula -

Current (I) = Charge (Q) / Time ( T ) or

Q = I x T

Substituting the values in the formula -

= 360/1200

= 36/120

= 3/10

= 0.3

Answer: The value of the current will be 0.3amp
