Pre-Test ELECTRIC CONDUCTION IN WIRES (L1)

What is the purpose for conducting the electric conduction in wires experiment?

• To understand Kirchoff's Law

• To understand Ohm's Law

• To understand Faraday's Law

• To understand Lenz's Law

What does Ohm's Law state?

• The electric current (I) through a conductor is proportional to the difference in electric

  voltage (V) across the conductor

• When an induced EMF arises in a circuit, the direction of the resulting induced current

  is such that it opposes the cause of the effect

• The current entering at the branch point is equal as the current leaving at the branch

  point

• The magnetic field around an electric current can be determined by its value

How does the electrical conduction in wires experiment work?

• Measure the temperature indicated on the temperature by varying the mass of water

• Measure the current indicated on the ammeter by varying the voltage

• Measure the temperature indicated on the temperature by varying the voltage

• Measure the current indicated on the ammeter by varying the voltage on the transformer

Below is an equation that states the amount of power dissipated is...

• V = I. R

• ∑ I_masuk = ∑ I_keluar

• P = V.I

• ∑ ε + ∑ I. R = 0

What tools are included in the practical module on electrical conductivity in wires?

• Lamp, transformer, voltmeter, and ammeter

• Transformer, voltmeter and ammeter, solenoid

• Lamp, voltmeter, ammeter, and regulator

• Transformer, voltmeter and ammeter, calorimeter

From the picture shown, What is the name of the tool indicated above is ...

• Ammeter

• Regulator

• Source of electrical voltage

• Voltmeter

The function of the tool indicated in image is

• Measuring the value of the electrical voltage in an electrical circuit in certain quantities and units.

• Measuring the value of electric current flowing in an electric circuit

• Reduces the voltage quickly if the generator is disconnected from the load which will result in over voltage

• Lowering or increasing the electrical voltage

The picture shows

• Connector

• Breadboard

• Led circuit

• Jumper cables

The following are the steps for assembling an electrical circuit:

1) Connect the positive voltmeter to the lamp.

2) Connect the positive ammeter to the negative voltmeter.

3) Connect ground to the negative of the ammeter

4) Connect ground to the negative of the voltmeter.

5) Connect the positive voltmeter to the electrical voltage source.

6) Connect the positive ammeter to the lamp.

Based on Chart I below, what is the correct order of arrangement?

• 3-2-6-1-5

• 4-2-6-1-5

• 1-5-4-2-6

• 2-6-1-5-4

If a% is the maximum error that we want, with the calculated value of a% in chart I being -20% and a% in chart II being -3% then the chart that must be chosen is...

• Charts I and II because they are not influential

• Chart II

• Chart I

• Must be checked again because it does not meet the requirements
