Question

How much voltage must be applied across a 0.20 Ω wire in order to create a 30 A current? (Please show work for it too)

Answer 1

Answer:

6 V

Explanation:

By ohm's law :

V = IR

V = 0.2 × 30 = 6 V

Answer 2

Answer:

V=6V

Explanation:

Use the equation I=V/R and solve for V then use V=IR plug in the numbers.

V=IR

V=30(0.2)

V=6V
