E = V1+V2+V3 = 15.
V1 = 3 Volts.
V2 = 10 Volts.
V3 = ?.
A 15-V battery is hooked up to three resistors in series. The voltage drop across the first resistor is 3V and the voltage drop across the sencond resistor is 10V. What is the voltage drop across the last resistor?
I don't understand what equation to do for this problem. Thanks.
