potential difference, current resistance definition, abbreviation units and symbol
- Potential difference: The difference in electric potential between two points in an electric circuit. It is measured in volts (V) and is commonly referred to as voltage. The symbol for potential difference is V.
- Current: The flow of electric charge in a circuit. It is measured in amperes (A) and is commonly referred to as current. The symbol for current is I.
- Resistance: The opposition to the flow of electric current in a circuit. It is measured in ohms (Ω) and is commonly referred to as resistance. The symbol for resistance is R.
- Abbreviation units:
- volts: V
- amperes: A
- ohms: Ω
1. Potential Difference:
Potential difference, also known as voltage, is the difference in electric potential energy between two points in an electric circuit. It represents the work done to move a unit charge from one point to another. Potential difference is measured in volts (V).
2. Current:
Current is the flow of electric charge through a conductor. It is the rate at which electric charges move past a specific point in a circuit. Current is measured in amperes (A).
3. Resistance:
Resistance is a measure of how strongly a conductor opposes the flow of electric current. It is caused by factors such as the material type, length, cross-sectional area, and temperature of the conductor. Resistance is measured in ohms (Ω).
