Question

find resistance of circut:-​

Answer 1

Explanation:

R2 and R3 are in series

r3= r2+r3 =5+5 =10 r=r1 + r2

R4 is parallel to (R2 and R3)

R4=10 r =( r1×r2)/(r1+r2)

r = 10×10/20

r =5

this total r is series with R1

R1+r = 5 +5 =10

total resistance is 10

voltage in the circuit is 10V

current = I =V/Total resistance

I = 10/10 = 1amps
