Question

In the circuit given below:
(a) What is the combined resistance ?
(b) What is the p.d. across the combined resistance ?
(c) What is the p.d. across the 3 ohm resistor ?
(d) What is the current in the 3 ohm resistor ?
(e) What is the current in the 6 ohm resistor ?​

Answer 1

a) resistors are connected in parallel

so, equivalent resistance = 1/3 + 1/6

= 2 ohm

b) By ohm's law,

V = iR

V = 6 × 2

V = 12 Volt

c) Potential difference in parallel remains constant, So potential difference across 3 ohm resistor is 12 Volt.

d) V = iR

i = V/R

i = 12 / 3

i = 4 Ampere

Current across 3 ohm resistor is 4 Ampere.

e) V = iR

i = V/R

i = 12 / 6

i = 2 Ampere

Current across 6 ohm resistor is 2 Ampere.

Hope it helps.........✌
