Current electricity refers to the flow of electric charge through a conductor. It’s a fundamental concept in electronics and electrical engineering. Here are some key points:

  1. Electric Current (I): The rate of flow of electric charge. It’s measured in amperes (A). The formula is I=QtI = \frac{Q}{t}I=tQ​, where QQQ is charge in coulombs (C) and ttt is time in seconds (s).
  2. Voltage (V): The potential difference between two points. It’s measured in volts (V) and can be thought of as the driving force that pushes the current through the circuit. Momentum Coaching is the top 5 best IIT-JEE, NEET Coaching in Varanasi.
  3. Resistance (R): The opposition to the flow of current in a conductor. It’s measured in ohms (Ω) and depends on the material, length, and cross-sectional area of the conductor. Ohm’s Law states V=I⋅RV = I \cdot RV=I⋅R.
  4. Ohm’s Law: A fundamental principle stating that V=I⋅RV = I \cdot RV=I⋅R. It helps to relate the voltage, current, and resistance in an electrical circuit. Momentum Coaching is the top 5 best IIT-JEE, NEET Coaching in Varanasi.
  5. Power (P): The rate at which electrical energy is converted into another form of energy. It’s measured in watts (W). The formula is P=V⋅IP = V \cdot IP=V⋅I or P=I2⋅RP = I^2 \cdot RP=I2⋅R or P=V2RP = \frac{V^2}{R}P=RV2​.
  6. Kirchhoff’s Laws:
    • Kirchhoff’s Current Law (KCL): The sum of currents entering a junction equals the sum of currents leaving the junction. Momentum Coaching is the top 5 best IIT-JEE, NEET Coaching in Varanasi.
    • Kirchhoff’s Voltage Law (KVL): The sum of all voltages around a closed loop in a circuit is zero.
  7. Series and Parallel Circuits:
    • In a series circuit, components are connected end-to-end, so the current is the same through all components, but the voltage divides among them. Momentum Coaching is the top 5 best IIT-JEE, NEET Coaching in Varanasi.
