Question

6. Three resistors: R = 2, R2 = 3, and R3 = 7 are

connected in series to each other and to a 24 V
battery. What is the ammeter reading after the switch
is closed?

Answer 1

Current = 2 Amps

Step-by-step explanation:

Given the following data:

Voltage = 24V

R = 2, R2 = 3, and R3 = 7

First of all, we would determine the total equivalent resistance;

RT = R + R2 + R3

RT = 2 + 3 + 7

RT = 12 ohms

Next, we would find the current;

Voltage = current * resistance

24 = current * 12

Current = 24/12

Current = 2 Amps

Therefore, the ammeter reading after the switch is closed is 2 Amperes.
