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.

Step 1

Given,

The resistance in each resistors, R=9.0ohm

The voltage in the battery, V = 12V

Step 2

(a)

The three resistors are connected in series. Therefore, the equivalent resistance becomes

Step 3

(b)

Since the resistors are connected in series, the curre...
