Question

2. For the circuit shown in below Figure, determine the p.d across resistor R3. If the
total resistance of the circuit is 100 ohm, determine the current flowing through
resistor R. Find also the value of resistor R2
R1 R2 R3
10v 4V V3
25v​

Answer 1

Answer:

GIVEN: V1= 10V , V2= 4V , V3=?

Total voltage (p.d)= 25V

Total resistance= 100 ohm

V=V1+V2+V3

25=10+4+V3

therefore,, V3= 25-14, V3= 11V

R=R1+R2+R3

R=V1/I +V2/I +V3/I

100 = 1/I (25)

therefore,, I = 25/100,= 0.25 A

NOW,,

R2 = V2/I , = 4/0.25= 4*100/25.

that is , R2= 16 ohm.
