A 15.0- resistor and a 20.0- resistor are connected in parallel. A 5.00- resistor is connected in series with this parallel arrangement. The resistors are connected across a 1.00 10^2-V battery. What is the current flowing through the 20.0- resistor? IS i...

A negatively charged balloon sticks to a wooden door. However, an unchanged balloon does not stick to a wooden door. What is the nature of the charge on the wooden door? Is it electrically neutral? Or could it possibly be possibly charged also?

I got it like this : two in parallel are equal to 15*20/35 = 8.57 ohms that in series with 5 ohms gives you 13.57 ohms I = E/R = 100/13.57 = 7.37 amps total current. voltage across parallel combo is E = IR = 7.37 x 8.57 = 63.1 volts current through 20 ohm...

Oh YEAH! I thought about the attracting I just didn't think about the repelling. THANKS :]
