Question

what happened when the name of electric what happened when a Ray of light is incident normally or rectangular glass slab how many 176 ohm resistors in parallel are required to carry 5A on a 220 volt​

Answer 1

For x number of resistors of resistance 176 Ω,

Here Supply voltage, V = 220 V

Current, I = 5 A

Equivalent resistance of the combination = R, given as

From Ohm’s law,

∴four resistors of 176 Ω are required to draw the given amount of current.
