Question

Find the amount of current flowing if 150 C charge flows for 15 min in
a) Ab) mA c) µA.

Answer 1

Explanation:

current= charge/time

Always take time in sec

time = 15*60

= 900sec

current= 150/900

= 0.16 Amphere

Now 1mA= 10 to the power -3 Amphere

Divide by 0.16 to the mA

=0.00016 mA

now 1micro amphere = 10to the power -6A

= 0.00000016
