Question

two copper wires a and b of resistance 40 ohm and 80 ohm respectively are connected in series to a supply of voltage 60v.what is the ratio of voltage across each resistor​

Answer 1

Answer:

It will be 20V and 40V respectively for 40 ohm and 80 ohm resistors

Explanation:

As the ratio of the resistance in the series is 40:80, it can be simplified to 1:2.

Now using basic unitary, we find that

3x (1+2) = 60

x = 20

therefore, it will be 20V : 40V
