Question

Which of the follwing statements are true or false and expain why

A. The connecting wirs in a circuit restrict or resist the movement of charge in a circuit?

B. The length of a connecting wire is a factor in the amount of charge moving through a cicuit

C.The type of wire used in a circuit affects the curent in the circuit

D. If the type of wire used affects the current in the circuit, if the more of that wire is used the greater the current

E. A bulb seems to limit or resist the movement of charge in a circuit

F. The cylinrical bulb restricts the movement of charge more than the round bulbs

G. The more bulbs connected in line in a circuit(in series), the higer the current

H. The curent on a circuit containing several round bulbs will be higher that the same circuit containing the same numbe of cylindrical bulbs

Explanation / Answer

1. true connecting wires do resist tthe movement of charge. However good the conductor might be it resist the passing of electrons unless it is a super conductor.

2. False: the length of a wire does not affect the amount of charge.

3. True: the type of wire will change the current since wires have resistances and different wires will have different resistance. This will be added to the resistive load of the circuit in series.

4. False: if more the wire used the greater the resistance since R=rho*l/A where l is the length of the wire and is directly proportiional to the length.

5. True: A bulb has certain amount of resistance which will restrict the electrons from passing.

6. False: it completely depends on the resitance values of the bulb.

7. False: The more the bulbs connected in series the more the resistance since it is added up and since I is inversely proportional the current will be lower.

8. False: the current will solely depend on the resistance values and not the shape of the bulb.
