A large number of AA batteries with emf E=1.5 V and resistors with resistance R form an infinite circuit . The internal resistance of the batteries is r. Thevenin's theorem tells us that this infinite circuit can be replaced by a single source with emf E_eq, connected in

series with an equivalent resistor R_eq. Determine the equivalent emf E_eq in volts if r/R=1/2.
