My question is this: what voltage must a battery have to support 10A of current trhough a light bulb with resistance 6 Ohms.
Is the answer simply found by: V = R x I ---- V = 6 x 10 = 60V
I believe this is correct.
Part II of my question is if you kept the same battery, but added a second light bulb in series, would the original bulb's brightness increase, decrease, or stay the same.
I believethat the original bulbs brightness would decrease because there is still only one source of energy, the battery, powering 2 light bulbs.
Can someone tell me if I am on the right track. Thank you so much!
