Question

The current in resistor Y is..?

Answer 1

The current in resistor Y is

a)1.0 A

Answer 2

(A)

Step-by-step explanation:

We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that

`P = VI`

Since resistor Y dissipates 100 W of power, we can solve for the current as

`I = (P)/(V) = \frac{100\:\text{W}}{100\:\text{V}} = 1.0\:\text{A}`
