When a pair of identical resistors are connected in series, which of the following is the same for both resistors: (a) voltage across each, (b) power dissipated in each, (c) current through each? Do any of your answers change if the resistors are different from each other?

Respuesta :

Answer:

(b) power dissipated in each.

(c) current through each.

Explanation:

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit.

Rt = R1 + R2

Vt = V1 + V2

Power dissipated is only the same if R1 = R2

Power, P = I^2R

If R1 is not equal to R2,

P1 = I^2 R1

P2 = I^2 R2

Therefore, P1 is not equal to P2
