1)A 15.0 resistor and a 20.0 resistor are connector in parallel. A 5.00 resistor is connected in series with this parallel arrangement. The resistors are connected across a 1.00(I think something else is suppose to be after that but its missing)10^2-V battery. What is the current flowing through the 20.0-resistor?
I got C.
2)A current of 5.0 A flows for 20.0 minutes through a bulb and delivers 15000 J of electric energy to the bulb. What is the potential difference across the bulb?
D)100 V (book typo)
I don't know what to do for this one
The first is wrong. I have no idea how you got that.
energy= V*I*timeinseconds solve for v
