Question

pls find total resistance​

Answer 1

Answer:

total resistance=50 ohm

Answer 2

Answer:

12.5Ω

Explanation:

Let R1= 20Ω

Let R2=5Ω

RS1= R1+R2= 20+5= 25Ω ( Since R1 and R2 are in series)

Let R3= 5Ω

Let R4= 20Ω

Let RS2= R3+R4= 5+20= 25Ω (Since R3 and R4 are in series)

1/RP= 1/RS1+ 1/RS2 (Since RS1 and RS2 are in parallel)

1/RP= 1/25+1/25

1/RP= 2/25

RP= 25/2= 12.5Ω
