Textbook Problem

# Three 9.0-Ω resistors are connected in series with a 12-V battery. Find (a) the equivalent resistance of the circuit and (b) the current in each resistor. (c) Repeat for the case in which all three resistors are connected in parallel across the battery.

(a)

To determine
The equivalent resistance of the circuit, that the resistors are connected in series.

Explanation

Given Info: The three 9.0â€‰Î© resistors are connected in series combination of the circuit

Explanation:

Since the three resistors are in series, the equivalent resistance of the circuit is,

Requ=R1+R2+R3

• Requ is the equivalent resistance,
• R1 , R2 , and R3 is the resistors connected in series combination,

Substitute 9

(b)

To determine
The current through each resistor in the series combination.

(c)

To determine
The equivalent resistance of the circuit, that the resistors are connected in parallel and current through each resistor.
