3. The load across a 12-V battery consists of a series combination of three resistors that have a resistance of 15 12,21 12, and 24 12,
respectively. What is the current in this circuit? (5F)
a. 0.2 A
b. 2.0 A
C. 0.19 A
d. 1.9 A

a. 0.2 A

Explanation:

Given;

voltage of the battery, V = 12 V

three resistance connected in series, R₁ = 15 Ω, R₂ = 21 Ω,   R₃ = 24Ω

The equivalent resistance for series connection is calculated as;

Rt = R₁ + R₂ +  R₃

Rt = 15Ω  +  21Ω   +   24Ω

Rt = 60 Ω

Apply Ohm's law to calculate the current n the circuit;

V = IRt

I = V/Rt

I = 12/60

I = 0.2 A

Therefore, the current in the circuit is 0.2 A

as technology advances, new experiments often expose problems in accepted theories. c
