Question

Q3. A charge of 90C passes through a wire in 1 hour and 15 minutes. What is the current in the wire?

​

Answer 1

Answer: The current in the wire is 72 Amperes (A).

Step-by-step explanation:

To find the current in the wire, we need to use the formula:

Current (I) = Charge (Q) / Time (t)

First, let's convert the time given from hours and minutes to hours:

1 hour and 15 minutes = 1.25 hours (since 15 minutes is equal to 0.25 hours)

Now we can calculate the current:

Current (I) = Charge (Q) / Time (t)

I = 90C / 1.25 hours

Dividing 90C by 1.25 hours:

I = 72 A
