Learning Task No. 3: Use the diagram showing the relationship among current,
resistance and voltage. Explain the relationship between
current and voltage;
voltage and resistance;
current and resistance.
Write your answer below

There is no diagram in this question, however, the question can be answered based on general understanding.

1. current and voltage; direct relationship

2. current and resistance; inverse relationship

3. voltage and resistance; direct relationship

Explanation:

The relationship between current (I), resistance (R) and voltage (V) has been explained by Ohms in his law. In Ohms law, which states that the current flowing through a circuit is directly proportional to the voltage and inversely proportional to the resistance.

This further means that if the voltage (V) increases, then the current (I) also increases and vice versa while if the resistance (R) is increased, the current (I) decreases and vice versa.

The equation represented by this law is:

V = IR or I = V/R or R = V/I

Likewise, the when the resistance is increased, the voltage increases and vice versa.

Therefore;

- Current (I) is directly proportional to the Voltage (V)

- Current (I) is inversely proportional to the Resistance (R)

- Voltage (V) is directly proportional to the Resistance (R)

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
