Answer:
B. 0.4A
Step-by-step explanation:
I've got that the answer is 0.4A. This is because current= voltage÷resitance
So, 1.2A=voltage÷resistance
However, if you only have 1/3 of the voltage AND the resistance remains constant, the current will change proportionally and will also decrease by 1/3 to give you 0.4A
