Problem 1
Current, I = 600A
Time, t = 20min
Each coulomb transport 1.2 mg of silver
∆𝑄
∆𝑡
Where ∆𝑄 is the charge in coulomb, C and ∆𝑡 is the time in seconds?
𝐼=
∆𝑄 = 𝐼 𝑥 ∆𝑡
∆𝑄 = 600𝐴 𝑥20 min 𝑥 60𝑠/𝑚𝑖𝑛
∆𝑄 = 720,000𝐶
If 1C transports 1.20mg of silver, What about 720,000C
Total weight of silver transported for one spoon:
720,000𝐶 𝑥 1.20𝑚𝑔
𝑊𝑠 =
= 864,000𝑚𝑔
1𝑐
If 864,000g are transported to one spoon, how about 1,000 spoons?
864,000𝑚𝑔 𝑥 1000 𝑠𝑝𝑜𝑜𝑛𝑠
𝑊𝑠1,000 =
= 864,000,000𝑚𝑔
1 𝑠𝑝𝑜𝑜𝑛
1kg = 1,000,000mg
864,000,000mg
Total weight for the 1,000 spoons is 864kg
Problem 2
Voltage source: 200V
Time: 3 hours
a =0.85m...
