Question

A 211-Ω and a 221-Ω resistor are connected in series across an unspecified power supply. If the current through the 211-Ω resistor is 0.22 A, what is the exact current (in A) through the 221-Ω resistor? Do not include units with your answer.

Answer 1

0.22 (A)

Step-by-step explanation:

Two resistors are connected in series when they are connected in the same branch of the circuit. When this occurs, we have the following:

- The current flowing through each resistor is the same (1)

- The total voltage of the circuit is the sum of the voltage drops across each resistor

- The total resistance of the circuit is equal to the sum of the individual resistances:

`R=R_1 + R_2`

So, given statement (1), in this case the current flowing through each resistor is the same, so the current flowing throught the 221-Ω resistor is also 0.22 A.
