Question

(1) Two resistors of resistance 4 ohm and 8 ohm are connected in parallel with a cell of emf 2v (i) calculate the equivalent resistance(ii) obtain current in 4 ohm and 8ohm resistors

Answer 1

Answer:

Explanation:

As the two resistors are in parallel so we calculate

1/4+1/8= 1/req

2+1/8=1/req

3/8=1/req

8/3=req

Now using the V=IR formula for finding the Current

In 4 ohm resistor

2 V= 4I

I=1/2A

In 8 ohm resistor

2V=8I

I=1/4A
