Question

One solar panel produces a potential difference
of 20V and current 4A. Describe now you can
obtain a potential difference of 80 Volts and
current of 12 A with a solar array using solar
panel. You can use sign of a battery for a solar
panel.​

Answer 1

Answer:

In a ( 4 × 3 ) combination

Explanation:

One solar panel  [ 20V   4A ]

If connected in series, then potential difference gets added

    ⇒ V = V₁ + V₂  But current remains the same i.e. I = I₁ = I₂

If connected in parallel, then current gets added

   ⇒ I = I₁ + I₂        But potential difference remains the same i.e. V =  V₁ = V₂

Thus first we can obtain 80 V by connecting 4 such solar panels in series

 ( 20 V × 4 = 80 V )

Now, we can obtain 12 A by connecting such 3 sets of 4 panels in parallel combination

( 4 A × 3 = 12 A )

Roughly, the solar array will look like  this

         ---║--║--║--║--  

         ---║--║--║--║--  

         ---║--║--║--║--  

         ---║--║--║--║--  

Thus, we get the required potential difference and current
