Current Electricity - Result Question 35

37. Current through $3 \Omega$ resistor is

Show Answer

Answer:

Correct Answer: 37. (c)

Solution:

  1. (c) Voltage across $3 \Omega$ resistance $=3 \times 0.8=$ 2.4V This voltage is the same across $6 \Omega$ resistance. Hence current through this resistance

$i=\frac{V}{R}=\frac{2.4}{6}=0.4 amp$

Total current in the circuit

$=0.8+0.4=1.2 amp$

Voltage across $4 \Omega$ resistance

$=4 \times 1.2=4.8$ volts
