(a) Suppose that you connect two identical flashlight batteries in series to get a 3-volt emf. Write a loop equation to
show that the maximum (short-circuit) current these batteries can deliver is exactly the same as the maximum
current from one battery.
(b) Alternatively, suppose that you connect two identical flashlight batteries in parallel, which gives you just a 1.5-volt
emf. Write loop and node equations to show that the maximum (short-circuit) current these batteries can deliver is
double that of one battery.
