Many people have the mistaken impression that current is used up around a circuit. In a  series circuit, for instance, is it true that the current decreases as it passes through the  resistors? What actually happens?

(a) Each of the following statements is incorrect. Correct the statements. (i) In a series circuits, current is used up as it flows through the resistors.(ii) In a parallel circuits, the current in each branch is the same as the current that flows into the junction before the branches.

Which of the following are characteristics of series circuits? Select all that apply. There are multiple paths for current to follow through the circuit. The voltage is divided among all devices in the circuit. If one device in the circuit stops allowing current to flow, all other devices in the circuit will also stop functioning. O The voltage across each device must be the same. O There is only one path for current to follow through the circuit. The same amount of current flows through all devices in the circuit.

QUESTION 31 In a series circuit with a large power source supplying voltage to a light bulb, as well as a switch, but the bulb keeps burning out as the current flow is too high. Which of the following electrical devices could you add to the circuit to prevent the bulb from burning out and why?     Another battery as this will increase the voltage and thereflow increase the current flow.     A resistor, because this will increase the circuit's resistance & decrease current flow.      A smaller light as this will increase the voltage and therefore the current flow.      A fuse as this will drop the current flow to zero.

In the circuit shown in the figure all resistors are 5 ohm resistors and the source EMF is 12 volts. (a) Calculate the equivalent resistance of the circuit below when the switch is (1) open (2) closed. (b) Calculate the Power in Rg and the current in R4 if the switch is (1) Open (2) Closed R1 si ww R2 R3 R5 R4

Help me answer this question, from my A-level physics class (Topic: AC Currents & Capacitors)
