Let's Check 5

In this activity, please write TRUE if the statement is true and write FALSE if the statement is false. This is to check your understanding of the concepts.

___________1. In the direct current, the direction of the current is opposite direction of the flow of electrons.

___________2. In the alternating current, the flow of the current reverses.

___________3. The drift speed of the charges is directly proportional to the area.

___________4. The current in inversely proportional to the amount of charge that pass through a conductor.

___________5. In the direct current, the electrons flow form negative terminal to positive terminal.

___________6. The emf pumps the electrons to increase its potential energy.

___________7. The battery has its internal resistance.

Let's Check 6

In this activity, please write TRUE if the statement is true and write FALSE if the statement is false. This is to check your understanding of the concepts.

______1. Resistance helps the current to flow very well.

______2. In a conducting wire, the higher the length of wire the higher the resistance will be produced.

______3. In a conducting wire, the bigger the diameter of wire the higher the resistance will be produced.

______4. If higher temperature will be introduced to conducting wire, the lower resistance will be produced.

______5. The resistivity s directly related to the resistance of a conducting wire.

Let's Check 7

In this activity, please write TRUE if the statement is true and write FALSE if the statement is false. This is to check your understanding of the concepts.

_____1. Voltage is directly proportional to current and resistance.

_____2. If resistance in the circuit increases, the current decreases.

_____3. If voltage increases in the circuit, the resistance increases.

_____4. The resistance must be lowered in order to allow the circuit better.

_____5. The SI unit of power is watts.

Let's Check 8

In this activity, please write TRUE if the statement is true and write FALSE if the statement is false. This is to check your understanding of the concepts.
