(D) 2, 3, and 4

Explanation:

Given that the connection is parallel,

The parallel circuit consisting of a battery, a switch, wires, and 5 bulbs has been shown in the figure.

But none of the bulbs light up upon completing the connection.

The given possible reasons are:

Option (1): One of the bulbs is burnt out.

As the connection is parallel, so the current from the battery is divided to all 5 bulbs, is one bulb is burnt out, it will not stop the current flowing through the other bulbs, so this is not the possible reason.

Option (2): One or more of the wires is not connected to the battery.

If one or more wire is not connected to the battery, then there will be no current in the circuit, so, no bulb will glow. Hence this may be the possible reason.

Option (3): The switch isn't properly closed.

If the switch isn't properly closed, then the circuit is not closed. Then there will be no current in the circuit, so, no bulb will glow. Hence this may be the possible reason.

Option (4): The resistance of the light bulbs prevents current from flowing through the circuit.

If the resistance of the bulb is very large and the current flowing in it is too less, then there will not be sufficient to glow the bulb. so, no bulb will glow. Hence this may be the possible reason.

So, the possible may be options (2), (3), and (4).

Hence, option (D) is correct.

Part 1: Answer the following questions (20 points)

1.Name and describe the components needed to make a complete circuit.

. battery

. connecting wire

. resister  

. voltmeter

. ammeter

2.Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.

They both give off electricity energy, and they are different because they don't release the same amount of energy

3.Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.

In accordance with the law, if r became smaller, and V stayed the same, the current would increase. The increases would be inversely proportional to the resistance, if the resistance was halved, the current would double.

4.Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it

part 1

1. You need a Source of electric power (battery or generator), a load to absorb the power (lamp, motor, heating coil) and wiring to connect the load to the power source!

2. they both give off electricity energy, and they are different because they dont release the same amount of energy

3. Current will increase

Explanation:

In Ohm's law the equation for current is current = voltage / resistance.

In order to explain how current is effected when resistance decreases while voltage stays the same, lets represents the situations with some possible inputs.

Let's compare 3 different closed circuits all with a voltage of 10V.

In circuit 1, the resistance is 5 ohm.

In circuit 2, the resistance is 2 ohms.

In circuit 3, the resistance is 1 ohms.

The current of:

Circuit 1 = Voltage / Resistance = 10 V / 5 ohms = 2 Amps

Circuit 2 = Voltage / Resistance = 10V / 2 ohms = 5 Amps

Circuit 3 = Voltage / Resistance = 10V / 1ohm = 10 Amps

As you can see in this representation, as the resistance in a circuit increases while the voltage is constant, the total current is increased.

4. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it.

If the voltage between the ends of a light bulb's filament

increases but the filament's resistance remains constant,

then the current through it increases by the same factor

as the voltage increase. The effect is to cause the light

to emit more light and heat ... both increase proportional

to the square of the voltage ... and possibly to "burn out".

Part 2

1. it's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor

2. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

3. The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.

4. the current runs through the motherboard and into the smaller components or the small internal wiring

5. A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.

Typical materials of a battery are as follows

- Anode most often is made of zinc

- Manganese dioxide acting as Cathode.

- the electrolyte between and inside contains ions
