Question

see image and find current and potential difference across them​

Answer 1

Explanation:

• All three 5 ohm resistors are connected in series

In series combination Equivalent Resistance

$Req = R1 + R2 + R3$

$Req = 5 + 5 + 5$

$Req = 15 \: ohm$

• By Ohm's Law

$v \: = i \: .Req$

$i \: = \frac{v}{Req}$

$i \: = \frac{15}{15}$

$i \: = 1 \: ampere$

• Since all resistors are connected in series so same current flow through them which is 1 Ampere
• By Ohm's Law

Potential Difference = i × R

= 1 × 5 = 5 Volt
