	All devices have internal resistance, except weird things like SQUIDs. What specifically are you looking for? __________________ "Well, I've wrestled with reality for 35 years, Doctor, and I'm happy to state I finally won out over it." Elwood P. Dowd

	of course the answer to the assignment given like most of the questions of this OP (see the next one or this for example) BTW- could you make head or tail of the question ? Either OP does not know what is a circuit or what is internal resistance or ... __________________ Fantastic ideas for a Fantastic World, I make the illogical logical.They put me in cars,they put me in yer tv.They put me in stereos and those little radios you stick in your ears.They even put me in watches, they have teeny gremlins for your watches

	One way to prove that everything has an internal resistance is to take a resistivity meter and measure your own . Disclaimer: being permanently sealed inside a robotic suit of armor means I can do this because I'm well-grounded. For those who are not, such as yourself, I cannot and will not guarantee that it won't be a real shocking experience . One final thing kid: stop writing here to ask us to do your homework assignments for you . Do them yourself first, and then post them here for us to verify them if you want . Reason ? Simple . You have absolutely no way of knowing if you get a sadistic jerk like yours truly who would deliberately give you answers that seem to make sense but are actually completely wrong just for the sake of his own personal amusement . __________________ If only you knew the power of the Dark Side of the Force
