Question

Find the current:
Resistance=12 OHMS
P.D.=8V​

Answer 1

Answer:

1 Ampere

Explanation:

2 resistor of 12 ohm are in series .

so they will give 12 + 12 =24 ohm.

this 24 ohm is in parallel with 12 ohm resistor

so resultant resistance is,

$\frac{1}{r} = \frac{1}{12} + \frac{1}{24}$

r= 8 ohm.

V= I x r

8 = I x 8

so I = 1 Ampere
