current x is 2.5 a and runs for 39 seconds. current y is 3.8 a and runs for 24 seconds. which current delivered more charge, and how much more charge did it deliver?\no x delivered 97.5 c more than y.\no x delivered 6.3 c more than y.\no y delivered 91.2 c more than x.\no y delivered 1.3 c more than x.
Answer
Explanation:
Step1: Calculate charge of X
Use formula $Q = It$, where $I$ is current and $t$ is time. For current X, $I_X=2.5$ A and $t_X = 39$ s. So $Q_X=I_Xt_X=2.5\times39 = 97.5$ C.
Step2: Calculate charge of Y
For current Y, $I_Y = 3.8$ A and $t_Y=24$ s. So $Q_Y=I_Yt_Y=3.8\times24=91.2$ C.
Step3: Find the difference
Calculate $Q_X - Q_Y=97.5 - 91.2=6.3$ C. Since $Q_X - Q_Y>0$, X delivered more charge.
Answer:
X delivered 6.3 C more than Y.
