V=IR

dan815 · Answer

ill wait

anonymous · Answer

ok,  but there are two voltages and two resitances.  i get V=IR.  don't understand how it works in this instance

dan815 · Answer

the more the resistance the more the voltage drop is

dan815 · Answer

basically 10 Voltages are dropped between these 2 resistors

dan815 · Answer

the bigger resistor will have a larger voltage drop proportional the resistors

anonymous · Answer

ok, how do you know it's 10 voltages dropped?
