Which of the following is true for a parallel circuit?

A.The current is the same across all resistors in the circuit.

B.The voltage is the same across all resistors in the circuit.

C.As more resistors are added, the current will decrease.

D.The sum of the voltage drops will equal the total voltage.

Respuesta :

B. The voltage is the same across all resistors in the circuit.

The correct answer is B

B. The voltage is the same across all resistors in the circuit

Basic characteristics of a parallel circuit is given as:

  • the voltage across the resistors is the same
  • the current across each resistor is different

The total current in a parallel circuit is given as:

[tex]I = I_1 + I_2 = \frac{V}{r_1} + \frac{V}{r_2} \\\\I = V (\frac{1}{r_1} + \frac{1}{r_2} )\\\\I = V(\frac{r_1 + r_2}{r_1r_2} )\\\\V = I(\frac{r_1r_2}{r_1 + r_2})[/tex]

Thus, the voltage in a parallel circuit increases as more resistors are added.

The only correct option that matches with above explanation is option B.
