Answer:
30 Coulombs
Explanation:
Given parameters:
Current  = 0.5A
Time  = 1min  = 60s
Unknown:
Charge that must pass through = ?
Solution:
The current in the circuit can be expressed using the equation below;
      I  = [tex]\frac{q}{t}[/tex] Â
I is the current, q is the charge and t is the time taken
 q  = current x time  = 0.5 x 60 = 30 coulombs
