1. The problem statement, all variables and given/known data I have learnt that current is constant throughout a series circuit, with or without resistors. Even if the no. of resistors in the circuit increases, the current is the same through each resistor. Resistors resist current flow, even though the current flowing through any point in the circuit remains the same as charge cannot"disappear", will the speed of the current remain the same through each resistor? An ammeter measures current, but does it measure the speed of current or the flow of current? When a circuit is complete, do the charges start flowing out from the battery cell or are there already charges in the wires in the circuit? I understand the current drawn and the current flowing through a series circuit is basically the same idea, but how does the current "see"the no. of resistors in the circuit and adjust its speed to fit the resistance in the whole circuit? Assuming voltage is constant.
