Question

Explain current and circuits with resistors connected in series and in parallel. Also give examples. (Please NOT by hand)

Answer 1

current is i

the resultant resistance is R

when resistors are conncted in series

R = R₁ + R₂ + ........

here using Ohm's Law we can write V = i R

i_series = V / R

i_series = V / R₁ + R₂ + ........

and sameway

when resistors are conncted in parallel

1 / R = 1/R₁ + 1/R₂ + ........

here using Ohm's Law we can write V = i R

i = V / R

i_parallel = V X (1/R₁ + 1/R₂ + ........)

finally we can conclude that,

when the resistors are connected in series the resistance is High and current is Low,

and

when the resistors are connected in parallel the resistance is Low and current is High.
