ahh what's the formula again?
V = IR
okay so whats V = IR from what you're given? Ignore the 1.5V for now
Given I = 2, R = 3
what V do you get from that?

i got 6V. I think its wrong
no that's right, since 2 * 3 = 6 Okay so now you have 6V which is the amount of battery used by the walkman
So how many 1.5V batteries you need to make it equal 6V?
4 i think
there you go :) 1.5 * 4 = 6
