A Radio Set Draws a Current of 0.36 a for 15 Minutes. Calculate the Amount of Electric Charge that Flows Through the Circuit. 

Advertisements

उत्तर

Given:
Current, I = 0.36 A
Time, t = 15 minutes = `(15xx60)` s = 900 s
Using the formula, `I=Q/t:`
or `Q=Ixxt=0.36xx900=324C`
 Thus, the amount of electric charge that flows through the circuit is 324 C.
