Question

A tablet draws 10.0 A when plugged into a 150-V line. If another tablet has twice as much resistance, what would the current of the second tablet be if plugged into the same line?
0.60 A
1.5 A
5 A
15 A

Answer 1

Answer:

5A

Explanation:

In case 1, I = 10A, V = 150volt

Using Ohms law, V = IR

R = V/I = 150/10 = 15 ohms

Case 2, when R is double

R = 15 ohms

I = V/R = 150/30 = 5A

Answer 2

Answer:

5 A
