A series circuit contains an electric generator, three devices operated by electricity, and the necessary connecting wires. The resistances of the three devices are 20 ohms, 8 ohms, and 4 ohms. The resistance of the connecting wires can be neglected. What is the total resistance in the circuit?

Respuesta :

Answer;

Total resistance = 32 ohms

Explanation;

The total resistance of a series circuit is equal to the sum of individual resistances.

That is;

Rt = R1 + R2 + R3 + R4 + .............Rn

Where, Rt is the total resistance of the circuit, while R1 , R2, R3 and R4 are the resistance of the components in the circuit and so fourth.

Thus;

Rt = 20Ω + 8Ω + 4Ω

   = 32 Ohms

Answer:

The total resistance is 32 Ohms

Explanation:

A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor.

The total resistance in a series circuit is given by

Rt = R1 + R2 + R3 and so on

So

Rt = 20 + 8 + 4 = 32 ohms
