What happens in a circuit when it needs more current?
I am wondering if with a circuit powered by a battery, would the battery always give out a fixed current? Or does the current outputted change on the components? E.G. if a LED needed 20A and 20A was being outputted form the battery, then another identical LED was added, would the current split between the two or would the battery double it's outputted current?
Thanks

Physics Question - Current in Resistor of parallel circuit - Need Help!?
Cannot see why it isn't 0.65. I worked out that the current for both parallel circuit and the 9 Ohm resistor is 0.75. So 32/37*0.75 =0.65 but it says it's incorrect. The hints don't help at all, so I was hoping someone could help me? Thank you
