Question

two resistors X And Y of resistances 2ohm and 3 ohm are joined to 5 voltage supply calculate the voltage accross the 3ohm resistor in the series combination

Answer 1

Answer:

3

Explanation:

By formula,

Voltage across 3ohms resister

= total voltage * that resistance/ total resistance

= 5*3/2+3

= 15/5

= 3

Answer 2

Answer:

here

the circuit is connected in series.

so,

R=3+2=5 ohm

V=5 V

we know,

$i = \frac{v}{r} = \frac{5}{5} = 1$

for X,

V1=6

R1=2

I = 1

so,

$v1- v2= ir \\ > 6 - v2 = 1 \times 2 \\ > 6 - v2 = 2 \\ > v2 = 4$

so Voltage experienced by 2nd resistance is 4V
