Question

current electricity​

Answer 1

Answer:

3 resistors are the diagram

Answer 2

Answer:

$\huge\star\underbrace{\mathtt\red{⫷❥ᴀ᭄} \mathtt\green{n~ }\mathtt\blue{ §} \mathtt\purple{₩}\mathtt\orange{Σ} \mathtt\pink{R⫸}}\star\:$

Explanation:

$\huge\underline{Given→}$

→Resistance=>7.2Ω(In series)

=>8Ω&12Ω(In parallel)

$\huge\underline{ToFind→}$

→Total Resistance=>R1+R2+R3

$\huge\underline{Answer→}$

→Parallel of R2 and R3=>R2R3/R2+R3

=>8*12/8+12

=>96/20

=>48/10

=>4.8Ω

→Series of R1 and R2=>R1+R2

=>7.2Ω+4.8Ω

=>12Ω

☞So 12Ω is the required total/effective resistance of the circuit.
