Question

study the following electrical circuit and find
1. current flowing through the circuit
2. the potential difference across 10 ohms resistor
I need answers with steps​

Answer 1

Answer:

Resistance ( parallel) :

1/R= 1/30 + 1/10 + 1/5

1/R= 10/30

R=3 ohms

1.) current in circuit = potintial difference / resistance

= 6/3

= 2 A

2.) when resistor are connected pallraly, potential difference remains same

Answer 2

Answer:

[1].V =ir  

V =10 ohm

0.1 A = I

V= 0.1 ×10 = 1 V ans

To find out current

I=V /R

3/30= 0.1 A

[2].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
