Question

Q26. Study the following electric circuit and find the
(1) current flowing through the circuit and
() the potential difference across 10 ohm resistor
​

Answer 1

Answer:

R = R1 + R2 = 10 + 20 = 30Ω

V = 3 V

(i) From ohm's law V = IR

3 = I × 30 ⇒ I = 3 / 30 = 1 / 10 Ampere or 0.1 A

(ii) Potential difference across 10Ω resistor

V = IR

= 1 / 10 = 1 volt
