Electric Current
- Definition: The flow of electric charge is known as Electric Current. It is carried by moving electrons through a conductor.
- Direction: By convention, electric current flows in the opposite direction to the movement of electrons.
- Electric Circuit: A continuous and closed path of electric current.
Expression of Electric Current
- Symbol: Electric current is denoted by the letter ‘I’.
- Formula: If a net electric charge (Q) flows through a conductor in time t, then
S.I. Units
- Electric Charge: Coulomb (C). 1 C=6×1018 electrons.
- Electric Current: Ampere (A). 1 A=1 C/s.
Small Quantities
- Milliampere (mA): 1 mA=10−3 A
- Microampere (μA): 1 μA=10−6 A
Instruments
- Ammeter: Measures electric current in a circuit.
Ammeter
Electric Charge and Potential
- Charge: Fundamental property of matter. Two types: Positive and Negative.
- Properties of Electric Charge:
- Unlike charges attract, like charges repel.
- Force between charges varies with the product of charges and inversely with the square of the distance.
Electric Potential and Potential Difference
- Electric Potential: Amount of electric potential energy at a point.
- Potential Difference (Voltage): Difference in electric potential energy between two points.
V=W/Q - S.I. Unit: Volt (V).
Instruments
- Voltmeter: Measures potential difference.
Voltmeter
- Galvanometer: Detects current in a circuit.
Galvanometer
Ohm’s Law
- Statement: Potential difference is directly proportional to electric current at constant temperature.
- Resistance: Property resisting electric current. Unit: Ohm (ΩΩ).
Factors Affecting Resistance
- Nature: Good conductors vs. insulators.
- Length: R ∝ l
- Area of Cross Section: R ∝ 1/A
- Specific Resistance (Resistivity):. Unit: Ω⋅m
. Unit: Combination of Resistors
Series Combination
- Total Resistance (Rs):Rs=R1+R2+R3.
Parallel Combination
- Inverse of Total Resistance
Heating Effect of Electric Current
- Joule’s Law: H=I2Rt
- Applications: Electric bulb, electric iron, electric heater.
Electric Power
- Definition: Work done per unit time. P=VI.
- S.I. Unit: Watt (W). 1 W=1 V×1 A.
- Kilowatt: 1 kW=1000 W.
Electric Energy
- Definition: Amount of work done to maintain continuous electric current.
- Unit: Joule (J).
Electric Power Consumption
- Unit: Kilowatt-hour (kWh). 1 kWh=3.6×106 J.
Conductors and Insulators
- Conductor: Allows flow of electrons. Low opposition to current.
- Insulator: Doesn't allow flow of electrons. High opposition to current.
Current Rating
- Definition: Maximum current without damaging the appliance.

FAQs on Important Equations and Definitions: Electricity - Science Class 10
| 1. What is electric current? |  |
Ans. Electric current refers to the flow of electric charge in a conductor. It is measured in Amperes (A) and is caused by the movement of electrons.
| 2. What is Ohm's Law? | |
Ans. Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across the conductor, given that the temperature and other physical factors remain constant. Mathematically, it can be expressed as I = V/R, where I is the current, V is the voltage, and R is the resistance.
| 3. How is electric power calculated? | |
Ans. Electric power is calculated using the formula P = VI, where P is the power, V is the voltage, and I is the current. It is measured in Watts (W) and represents the rate at which electric energy is converted into other forms, such as heat or mechanical work.
| 4. What are conductors and insulators? | |
Ans. Conductors are materials that allow the flow of electric charge easily, as they have loosely bound electrons. Examples include metals like copper and aluminum. On the other hand, insulators are materials that do not allow the flow of electric charge easily, as they have tightly bound electrons. Examples include rubber, glass, and plastic.
| 5. What is the heating effect of electric current? | |
Ans. The heating effect of electric current refers to the phenomenon where the flow of electric current through a conductor produces heat. This effect is utilized in appliances like electric heaters and toasters. The amount of heat produced is directly proportional to the square of the current, resistance, and time duration. It can be calculated using the formula H = I^2RT, where H is the heat produced, I is the current, R is the resistance, and T is time.
