Answer 1

Answer: 20 A

Concept: Ohm’s Law

The relationship between electric current and a potential difference is stated by Ohm's law. Most conductors have a direct relationship between the voltage applied to them and the current that flows through them.

Given: R1= 2Ω  R2=3Ω R3= 6Ω  V= 20 V

To Find: Current (I)

Step-by-step explanation:

As the three resistances i.e. R1, R2, and R3 are connected in parallel series, we will first find the overall resistance.

1/RP= 1/R1+1/R2+1/R3

1/RP=½+⅓+⅙

1/RP= 3+2+⅙

1/RP= 6/6

RP=1 Ω

Now, as per Ohm’s law

V=IR

Where, V= Potential difference, I = Current, R= Resistance

Now, placing the values in the above formula

We get

20=(I) 1

I= 20 A

The electric current in the circuit is = 20 A
