The question asks which law states that the current flowing into a junction must be equal to the current flowing out of it.
- Kirchhoff's Current Law (KCL): This law states that the algebraic sum of currents entering a node (or junction) is equal to zero. In simpler terms, the total current flowing into a junction must equal the total current flowing out of that junction. This is based on the principle of conservation of charge.
- Kirchhoff's Voltage Law (KVL): This law states that the algebraic sum of all voltages around any closed loop in a circuit must equal zero.
- Ohm's Law: This law states the relationship between voltage, current, and resistance: V = IR.
- Faraday's Law: This law describes the relationship between a changing magnetic field and the electric field it induces.
The description perfectly matches Kirchhoff's Current Law (KCL).
The law that states that the current flowing into a junction must be equal to the current flowing out of it is Kirchhoff's Current Law (KCL).
In the given circuit the sliding contact is pulled outwards such that the electric current in the circuit changes at the rate of 8 A/s. At an instant when R is 12 Ω, the value of the current in the circuit will be A.
