**bobpursley**, Monday, May 24, 2010 at 6:33pmThere is a formula you can use, but instead, do this:

assume 150 volts>

Current in 10 ohm resistor= 15a

current in 15 ohm reistor= 10 a

Net resistance= V/I= 150/25=6 ohms

and of course, you can do it the geek way:

1/Rtotal= 1/10 + 1/15

1/Rtotal= (15+10)/150= 1/6

Rtotal= 6 ohms.
