Question

1. in rl series circuits, __________. a current is the same at any point in the circuit b voltage is the same at any point in the circuit c resistance is the same at any point in the circuit d current is different at any point in the circuit

Explanation:

In a series circuit (including RL series circuits), the current has only one path to flow. According to Kirchhoff's current law, the current is the same at any point in a series circuit. Voltage across components (resistor and inductor here) can be different as \(V = IR\) (for resistor, \(R\) is resistance) and \(V = L\frac{di}{dt}\) (for inductor, \(L\) is inductance). Resistance of resistor and inductance (which can be considered as a kind of opposition in AC, but in general DC - like analysis for current - same - property, resistance of resistor and inductive reactance are different quantities).

Answer:

A. current is the same at any point in the circuit
