For #2 if you put the ammeter connecting directly with other light bulbs and resistors you'd be able to get the current from power source. Since in a series circuit all the current must be the same therefore I guess in series circuit it doesn't matter but the upper part of the diagram which is a...
Power Source at 6.0V
a) Voltage drop across the parallel branch of the circuit: 0.25V
b) Voltage drop across the light bulb connected in parallel: 0.25V
c) Voltage drop across the light bulb connected in series: 0.5V
2) How would you measure the current through the entire circuit: By putting...
