1. The problem statement, all variables and given/known data

A) What is voltage V at terminal A with respect to ground?

B) Imagine that a wire is connected between terminals A and B. What is the current flowing through the battery?

C) With the wire connected between terminals A and B, what is the current flowing through the 2 Ω resistor?

D) Imagine that, instead of a wire, a 6Ω resistor is connected between terminals A and B. What is the current flowing through the battery?

2. Relevant equations

V=IR

3. The attempt at a solution

For part A, I know that the ground is the symbol at the bottom, but I do not know how to calculate the voltage.

For part B, I thought the answer would be 5A because V=IR gives 10=2I so I is 5, but that is incorrect.

For part C, I applied the same reasoning in B and that was wrong again.

For part D, I got 10=6I, which would give 1.67 but that's wrong.

Can someone please help me understand the concepts? I think that would provide a good start. I thought I just had to apply Ohm's Law but is there something more I must do?? Thanks.
