I got a circuit below and just wondering if i got the concept of open circuit correct. So i understand that the 10V and 2.7k ohm resistor has no drop and no current between them and the rest of the resistors will experience voltage drops from the 24V source correct? Its asking me to find the potential difference between point b and point e. So would i just find the potential at point b and just subtract it by 10? from what i learned that there is still voltage across the wire just no current so the potential at point e would be 10 volts? correct? and also what would a volt meter read if i put it between D and C? is it 10V - the drop from point C to F? or is it just 10 volts? Thanks for the help!
