Question

Three resistance of value 12 ohm,3ohm and 15ohm are connected in series across 20v ,D.C supply calculated
a. equivalent resistance of the circuit
b. the total current of the circuit
c.the voltage drop across each resistor.​

Answer 1

Explanation:

1.

a. 12+ 3+ 15 =30 ohm

b. i = 2/3

c. v1= 12v

v2 = 2v

v3 = 6v

Answer 2

Answer:

a. 30 ohm

b. 2/3 ampere

c. 8V , 2V and 10 V

Explanation:

a. Req. = 12+3+15 = 30 ohm

b. Total current(I) = V/R = 20/30 = 2/3 ampere

c. Voltage across 12 ohm = 2/3×12 = 8V

Voltage across 3 ohm = 2/3×3 = 2V

Voltage across 15 ohm = 2/3×15 = 10V
