PLS HELP I WILL GIVE THE BRAINLIEST ANSWER
seropon [69]

Answer:

6

Step-by-step explanation:

If V = IR, then V = 40 * 3 in this case, which means V = 120. Quote question, "Assume voltage remains constant." This means V still equals 120 in the second scenario, which we can input into I = V / R to make I = 120 / 20 = 6.

Hope this helps!
