Question

two resistance of 10 ohm and 20 ohm are connected is series a potential difference across both the resistance is 3 ampere calculate total current across the circuit and find the potential difference across 10 ohm resistance​

Answer 1

Answer:so the current in Resistor 10 ohm is 4ampere and in Resistor 20 ohm is 2 ampere

Explanation:

since the connection is in parallel then it's

1/Rt=1/r1+1/r2

1/Rt=1/10+1/20

1/Rt=(2+1)/20

1/Rt=3/20

Rt=20/3ohms

but

V=IR but I=6 ampere

V=6×20/3 V

V=40v

but we are asked the current in each resistor so

for R=10ohm

I=V/R

I=40v/10ohm

I=4ampere

for R=20ohm

I=V/R

I=40/20ampere

I=2ampere
