| Answer» <p>Question- An electric bulb draws a current of 0.25 A for 20 minutes. Calculate the amount of electric charge that flows through the circuit.</p><p>Solution:According to question,Current, I=0.25 ATime, t=20 minutes=20 x 60 seconds [As, 1 minute=60 seconds]=1200 secondsNow, we have a relation,I=Q/tOr Q=I x tPutting the values, we getQ=0.25 x 1200=300 coulombsTherefore, the amount of charge that flows through the circuit is 300 coulombs.</p> <p>300 Columbus is a right answer</p> | |
